Apache2 default project to be used

It is my understanding that we were using a fork of the apache2 project because we need apache available before running the disable-cdn recipe of the drupal-site-jnl-elife-cookbook

But I have tested the setup of the site from scratch locally and aws and the disable-cdn recipe runs fine and I have verified that the cdn modules is disabled in both cases.

If this is accepted then we can delete the apache2 forked repo on the elifesciences account.
