Initial commit for CentOS AFS mirror

This is the first step to getting an AFS mirror for centos going. We
still need to add RPM validation and enabled automatic vos release.

However, this will atleast enabled us to do the initial import of the
RPMs into AFS which will take a few days to mirror properly.
