Implement cloudforms license

This is a special license that is triggered in the presence of two
directories:
  - /opt/rh/cfme-appliance
  - /opt/rh/cfme-gemset
and the rpms
  - cfme
  - cfme-appliance
  - cfme-gemset

All of which I'm assured are responsible for validating that this is
indeed an enterprise cloudforms environment.

When these are present then a license is used that is near perpetual,
allows for a stupid large number of instances, and turns on all features
