Allow Custom Apache VHOST directives to be included

[jaydrogers]

Problem

• There isn't an easy way to include simple configuration additions to the Apache sites

What this PR does

• [X] Create a new folder called /etc/apache2/custom-vhost-conf
• [X] Set the Apache configurations to scan that folder for any file ending in *.conf
• [ ] Include those settings to be loaded within the Virtual Host Directive
