Dean Troyer e4fa721322 Begin is_service_enabled() cleanup
This converts the special cases in the is_service_enabled() function to call
individual functions declared by the projects.  This allows projects that
are not in the DevStack repo and called via the extras.d plugin to handle
an equivalent service alias.

* Ceilometer
* Cinder
* Glance
* Neutron
* Nova
* Swift

TODO: remove the tests from is_service_enabled() after a transition period

Patch Set 2: Rebased
