Fix whitespace in many administration docs

Many code blocks are 4spaced, and they render in GitLab
without coloring as a result, even though they are
fenced with a language label. If in a list, other items
will render as being in a code block too, even if not
meant to. This fixes all these issues for many admin
docs (part 2)

 1. First, download the package and install the required packages:
 
-    ```
-    sudo su -
-    cd /tmp
-    curl --remote-name https://mirrors.evowise.com/pub/OpenBSD/OpenSSH/portable/openssh-7.5p1.tar.gz
-    tar xzvf openssh-7.5p1.tar.gz
-    yum install rpm-build gcc make wget openssl-devel krb5-devel pam-devel libX11-devel xmkmf libXt-devel
-    ```

+   yum install rpm-build gcc make wget openssl-devel krb5-devel pam-devel libX11-devel xmkmf libXt-devel
+   ```
 
 1. Prepare the build by copying files to the right place:
 
-    ```
-    mkdir -p /root/rpmbuild/{SOURCES,SPECS}
-    cp ./openssh-7.5p1/contrib/redhat/openssh.spec /root/rpmbuild/SPECS/
-    cp openssh-7.5p1.tar.gz /root/rpmbuild/SOURCES/
-    cd /root/rpmbuild/SPECS
-    ```
+   ```
+   mkdir -p /root/rpmbuild/{SOURCES,SPECS}
+   cp ./openssh-7.5p1/contrib/redhat/openssh.spec /root/rpmbuild/SPECS/
+   cp openssh-7.5p1.tar.gz /root/rpmbuild/SOURCES/
+   cd /root/rpmbuild/SPECS
+   ```
 
 1. Next, set the spec settings properly:
 
-    ```
-    sed -i -e "s/%define no_gnome_askpass 0/%define no_gnome_askpass 1/g" openssh.spec
-    sed -i -e "s/%define no_x11_askpass 0/%define no_x11_askpass 1/g" openssh.spec
-    sed -i -e "s/BuildPreReq/BuildRequires/g" openssh.spec
-    ```
+   ```
+   sed -i -e "s/%define no_gnome_askpass 0/%define no_gnome_askpass 1/g" openssh.spec
+   sed -i -e "s/%define no_x11_askpass 0/%define no_x11_askpass 1/g" openssh.spec
+   sed -i -e "s/BuildPreReq/BuildRequires/g" openssh.spec
+   ```
 
 1. Build the RPMs:
 
-    ```
-    rpmbuild -bb openssh.spec
-    ```
+   ```
+   rpmbuild -bb openssh.spec
+   ```
 
 1. Ensure the RPMs were built:
 
-    ```
-    ls -al /root/rpmbuild/RPMS/x86_64/

 1. Install the packages. OpenSSH packages will replace `/etc/pam.d/sshd`
    with its own version, which may prevent users from logging in, so be sure
    that the file is backed up and restored after installation:
 
-    ```
-    timestamp=$(date +%s)
-    cp /etc/pam.d/sshd pam-ssh-conf-$timestamp
-    rpm -Uvh /root/rpmbuild/RPMS/x86_64/*.rpm
-    yes | cp pam-ssh-conf-$timestamp /etc/pam.d/sshd
-    ```
+   ```
+   timestamp=$(date +%s)
+   cp /etc/pam.d/sshd pam-ssh-conf-$timestamp
+   rpm -Uvh /root/rpmbuild/RPMS/x86_64/*.rpm
+   yes | cp pam-ssh-conf-$timestamp /etc/pam.d/sshd
+   ```
 
 1. Verify the installed version. In another window, attempt to login to the server:
 
-    ```
-    ssh -v <your-centos-machine>
-    ```
+   ```
+   ssh -v <your-centos-machine>
