Removal of config manipulation for apache2

As discussed on IRC we can remove the manipulation of the config files
here. The deployment tool is in full control of what configs are read.
We strongly recommend any deploy project using multiple distros
architect deploying using the appropriate flags available for control
over configs rather than trusting the distros default configs since the
defaults are different per distro.
