Add flag to disable EPEL

Browse Source 
Add DIB_EPEL_DISABLED flag that allows installation of the EPEL repo,
but to have it disabled by default.  This will help when you have
unavoidable EPEL dependencies, but want to make sure you only pull
specific things in with "--enablerepo" calls when installing those
packages.
