Refactor the upgrading from source docs

Instead of requiring one separate document for every version (which is
created by release managers), we now use a single document for both
Community Edition and Enterprise Edition. This allows developers to add
guidelines right away, instead of release managers having to determine
what to add.

Version specific upgrading instructions are placed in a separate
section. This prevents instructions from lingering around for many
versions should a developer forget to remove them. This also ensures
that all instructions are kept in a single place, instead of being
spread across different documents.

A minor downside is that CE and EE guidelines now live in the same
document, which could cause merge conflicts. Since we are working
towards a single codebase, this should only be an issue until we merge
the codebases together; something we expect to do in the coming months.

This commit also removes all old upgrading instructions, but these can
still be accessed using Git branch specific URLs (included in the
updating README).

-# From 10.7 to 10.8
-
-Make sure you view this update guide from the tag (version) of GitLab you would
-like to install. In most cases this should be the highest numbered production
-tag (without rc in it). You can select the tag in the version dropdown at the
-top left corner of GitLab (below the menu bar).
-
-If the highest number stable branch is unclear please check the
-[GitLab Blog](https://about.gitlab.com/blog/archives.html) for installation
-guide links by version.
-
-### 1. Stop server
-
-```bash
-sudo service gitlab stop
-```
-
-### 2. Backup
-
-NOTE: If you installed GitLab from source, make sure `rsync` is installed.
-
-```bash
-cd /home/git/gitlab
-
-sudo -u git -H bundle exec rake gitlab:backup:create RAILS_ENV=production
-```
-
-### 3. Update Ruby
-
-NOTE: GitLab 9.0 and higher only support Ruby 2.3.x and dropped support for Ruby 2.1.x. Be
-sure to upgrade your interpreter if necessary.
-
-You can check which version you are running with `ruby -v`.
-
-Download Ruby and compile it:
-
-```bash
-mkdir /tmp/ruby && cd /tmp/ruby
-curl --remote-name --progress https://cache.ruby-lang.org/pub/ruby/2.3/ruby-2.3.7.tar.gz
-echo '540996fec64984ab6099e34d2f5820b14904f15a  ruby-2.3.7.tar.gz' | shasum -c - && tar xzf ruby-2.3.7.tar.gz
-cd ruby-2.3.7
-
-./configure --disable-install-rdoc
-make
-sudo make install
-```
-
-Install Bundler:
-
-```bash
-sudo gem install bundler --no-document --version '< 2'
-```
-
-### 4. Update Node
-
-GitLab utilizes [webpack](http://webpack.js.org) to compile frontend assets.
-This requires a minimum version of node v6.0.0.
-
-You can check which version you are running with `node -v`. If you are running
-a version older than `v6.0.0` you will need to update to a newer version. You
-can find instructions to install from community maintained packages or compile
-from source at the nodejs.org website.
-
-<https://nodejs.org/en/download/>
-
-GitLab also requires the use of yarn `>= v1.2.0` to manage JavaScript
-dependencies.
-
-```bash
-curl --silent --show-error https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -
-echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list
-sudo apt-get update
-sudo apt-get install yarn
-```
-
-More information can be found on the [yarn website](https://yarnpkg.com/en/docs/install).
-
-### 5. Update Go
-
-NOTE: GitLab 9.2 and higher only supports Go 1.8.3 and dropped support for Go
-1.5.x through 1.7.x. Be sure to upgrade your installation if necessary.
-
-You can check which version you are running with `go version`.
-
-Download and install Go:
-
-```bash
-# Remove former Go installation folder
-sudo rm -rf /usr/local/go
-
-curl --remote-name --progress https://storage.googleapis.com/golang/go1.8.3.linux-amd64.tar.gz
-echo '1862f4c3d3907e59b04a757cfda0ea7aa9ef39274af99a784f5be843c80c6772  go1.8.3.linux-amd64.tar.gz' | shasum -a256 -c - && \
-  sudo tar -C /usr/local -xzf go1.8.3.linux-amd64.tar.gz
-sudo ln -sf /usr/local/go/bin/{go,godoc,gofmt} /usr/local/bin/
-rm go1.8.3.linux-amd64.tar.gz
-```
-
-### 6. Get latest code
-
-```bash
-cd /home/git/gitlab
-
-sudo -u git -H git fetch --all --prune
-sudo -u git -H git checkout -- db/schema.rb # local changes will be restored automatically
-sudo -u git -H git checkout -- locale
-```
-
-For GitLab Community Edition:
-
-```bash
-cd /home/git/gitlab
-
-sudo -u git -H git checkout 10-8-stable
-```
-
-OR
-
-For GitLab Enterprise Edition:
-
-```bash
-cd /home/git/gitlab
-
-sudo -u git -H git checkout 10-8-stable-ee
-```
-
-### 7. Update gitlab-shell
-
-```bash
-cd /home/git/gitlab-shell
-
-sudo -u git -H git fetch --all --tags --prune
-sudo -u git -H git checkout v$(</home/git/gitlab/GITLAB_SHELL_VERSION)
-sudo -u git -H bin/compile
-```
-
-### 8. Update gitlab-workhorse
-
-Install and compile gitlab-workhorse. GitLab-Workhorse uses
-[GNU Make](https://www.gnu.org/software/make/).
-If you are not using Linux you may have to run `gmake` instead of
-`make` below.
-
-```bash
-cd /home/git/gitlab-workhorse
-
-sudo -u git -H git fetch --all --tags --prune
-sudo -u git -H git checkout v$(</home/git/gitlab/GITLAB_WORKHORSE_VERSION)
-sudo -u git -H make
-```
-
-### 9. Update Gitaly
-
-#### New Gitaly configuration options required
-
-In order to function Gitaly needs some additional configuration information. Below we assume you installed Gitaly in `/home/git/gitaly` and GitLab Shell in `/home/git/gitlab-shell`.
-
-```shell
-echo '
-[gitaly-ruby]
-dir = "/home/git/gitaly/ruby"
-
-[gitlab-shell]
-dir = "/home/git/gitlab-shell"
-' | sudo -u git tee -a /home/git/gitaly/config.toml
-```
-
-#### Check Gitaly configuration
-
-Due to a bug in the `rake gitlab:gitaly:install` script your Gitaly
-configuration file may contain syntax errors. The block name
-`[[storages]]`, which may occur more than once in your `config.toml`
-file, should be `[[storage]]` instead.
-
-```shell
-sudo -u git -H sed -i.pre-10.1 's/\[\[storages\]\]/[[storage]]/' /home/git/gitaly/config.toml
-```
-
-#### Compile Gitaly
-
-```shell
-cd /home/git/gitaly
-sudo -u git -H git fetch --all --tags --prune
-sudo -u git -H git checkout v$(</home/git/gitlab/GITALY_SERVER_VERSION)
-sudo -u git -H make
-```
-
-### 10. Update MySQL permissions
-
-If you are using MySQL you need to grant the GitLab user the necessary
-permissions on the database:
-
-```bash
-mysql -u root -p -e "GRANT TRIGGER ON \`gitlabhq_production\`.* TO 'git'@'localhost';"
-```
-
-If you use MySQL with replication, or just have MySQL configured with binary logging,
-you will need to also run the following on all of your MySQL servers:
-
-```bash
-mysql -u root -p -e "SET GLOBAL log_bin_trust_function_creators = 1;"
-```
-
-You can make this setting permanent by adding it to your `my.cnf`:
-
-```
-log_bin_trust_function_creators=1
-```
-
-### 11. Update configuration files
-
-#### New configuration options for `gitlab.yml`
-
-There might be configuration options available for [`gitlab.yml`][yaml]. View them with the command below and apply them manually to your current `gitlab.yml`:
-
-```sh
-cd /home/git/gitlab
-
-git diff origin/10-7-stable:config/gitlab.yml.example origin/10-8-stable:config/gitlab.yml.example
-```
-
-#### Nginx configuration
-
-Ensure you're still up-to-date with the latest NGINX configuration changes:
-
-```sh
-cd /home/git/gitlab
-
-# For HTTPS configurations
-git diff origin/10-7-stable:lib/support/nginx/gitlab-ssl origin/10-8-stable:lib/support/nginx/gitlab-ssl
-
-# For HTTP configurations
-git diff origin/10-7-stable:lib/support/nginx/gitlab origin/10-8-stable:lib/support/nginx/gitlab
-```
-
-If you are using Strict-Transport-Security in your installation to continue using it you must enable it in your Nginx
-configuration as GitLab application no longer handles setting it.
-
-If you are using Apache instead of NGINX please see the updated [Apache templates].
-Also note that because Apache does not support upstreams behind Unix sockets you
-will need to let gitlab-workhorse listen on a TCP port. You can do this
-via [/etc/default/gitlab].
-
-[Apache templates]: https://gitlab.com/gitlab-org/gitlab-recipes/tree/master/web-server/apache
-[/etc/default/gitlab]: https://gitlab.com/gitlab-org/gitlab-ce/blob/10-8-stable/lib/support/init.d/gitlab.default.example#L38
-
-#### SMTP configuration
-
-If you're installing from source and use SMTP to deliver mail, you will need to add the following line
-to config/initializers/smtp_settings.rb:
-
-```ruby
-ActionMailer::Base.delivery_method = :smtp
-```
-
-See [smtp_settings.rb.sample] as an example.
-
-[smtp_settings.rb.sample]: https://gitlab.com/gitlab-org/gitlab-ce/blob/10-8-stable/config/initializers/smtp_settings.rb.sample#L13
-
-#### Init script
-
-There might be new configuration options available for [`gitlab.default.example`][gl-example]. View them with the command below and apply them manually to your current `/etc/default/gitlab`:
-
-```sh
-cd /home/git/gitlab
-
-git diff origin/10-7-stable:lib/support/init.d/gitlab.default.example origin/10-8-stable:lib/support/init.d/gitlab.default.example
-```
-
-Ensure you're still up-to-date with the latest init script changes:
-
-```bash
-cd /home/git/gitlab
-
-sudo cp lib/support/init.d/gitlab /etc/init.d/gitlab
-```
-
-For Ubuntu 16.04.1 LTS:
-
-```bash
-sudo systemctl daemon-reload
-```
-
-### 12. Install libs, migrations, etc.
-
-```bash
-cd /home/git/gitlab
-
-# MySQL installations (note: the line below states '--without postgres')
-sudo -u git -H bundle install --without postgres development test --deployment
-
-# PostgreSQL installations (note: the line below states '--without mysql')
-sudo -u git -H bundle install --without mysql development test --deployment
-
-# Optional: clean up old gems
-sudo -u git -H bundle clean
-
-# Run database migrations
-sudo -u git -H bundle exec rake db:migrate RAILS_ENV=production
-
-# Compile GetText PO files
-
-sudo -u git -H bundle exec rake gettext:compile RAILS_ENV=production
-
-# Update node dependencies and recompile assets
-sudo -u git -H bundle exec rake yarn:install gitlab:assets:clean gitlab:assets:compile RAILS_ENV=production NODE_ENV=production
-
-# Clean up cache
-sudo -u git -H bundle exec rake cache:clear RAILS_ENV=production
-```
-
-**MySQL installations**: Run through the `MySQL strings limits` and `Tables and data conversion to utf8mb4` [tasks](../install/database_mysql.md).
-
-### 13. Start application
-
-```bash
-sudo service gitlab start
-sudo service nginx restart
-```
-
-### 14. Check application status
-
-Check if GitLab and its environment are configured correctly:
-
-```bash
-cd /home/git/gitlab
-
-sudo -u git -H bundle exec rake gitlab:env:info RAILS_ENV=production
-```
-
-To make sure you didn't miss anything run a more thorough check:
-
-```bash
-cd /home/git/gitlab
-
-sudo -u git -H bundle exec rake gitlab:check RAILS_ENV=production
-```
-
-If all items are green, then congratulations, the upgrade is complete!
-
-## Things went south? Revert to previous version (10.7)
-
-### 1. Revert the code to the previous version
-
-Follow the [upgrade guide from 10.6 to 10.7](10.6-to-10.7.md), except for the
-database migration (the backup is already migrated to the previous version).
-
-### 2. Restore from the backup
-
-```bash
-cd /home/git/gitlab
-
-sudo -u git -H bundle exec rake gitlab:backup:restore RAILS_ENV=production
-```
-
-If you have more than one backup `*.tar` file(s) please add `BACKUP=timestamp_of_backup` to the command above.
