Add acme library usage example (http-01) (#5494)

* Add acme library usage example

Create, edit and deactivate account.
Setup and perform http-01 challenge.
Issue, renew and revoke certificate.

* Adapt example to ACME-v2 and exclude data persistence

The code to persist/load data would length this example and distract from what is actually important.

* Fix domain names and e-mail addresses

* Remove unnecessary license header

This usage example is under the license for the acme package.

* Remove logging information

The code will be mostly read by developers, so simplify the logging info into comments.

* Revert abstraction of simple methods

All methods that are used only once in this example were expanded into the main code in order to make the process more explicit.

* Fix missing URL suffix

* Improve aesthetics and reorganize workflow

Also make words capitalization consistent and improve comments.
No complaints from pep8.
