Put our ansible roles in standard location

[kbrock]

related: ManageIQ/manageiq-rpm_build#159

using standard ansible configuration and removed special
configuration file.

we removed this to get away from a root specific configuration
which is necessary as we go towards running this as manageiq user

@kbrock can we mark this as [WIP] until the RPM build PR is in place, and mark that PR as a prerequisite for this one? Otherwise code that relies on our custom roles will not work on the interim if a build goes out without.

I don’t expect there to be much of a hold up with the RPM PR once we can validate that, but they should be merged in close proximity and marked as dependent on case they are flagged for backport.
