rpm: Enable creation of RPMs

This is the first step.  I have confirmed that I can install,
update, and remove.  I have also setup the ability for Jenkins
to pass the BuildNumber and use that value as the release
number for the RPM.

The RPM depends on Grizzly(1.8.0) Swift from OpenStack.  To verify
you may need to add the appropiate repo file to your Fedora/RHEL system:
http://repos.fedorapeople.org/repos/openstack/openstack-grizzly

I have not had the opportunity to test that G4S itself works
once installed, but I plan on doing that as the next phase.
