Add all neutron packages to requirements

It has come up in several requests that we should have packages present for
 all of the neutron components so that any patches we might have included are
 present in the repos on the fuel-master.

This is not intended to be a "fuel suppports ..." but rather enables users to
 customize their deployment accordingly and not have to find packages that
 where not built from the same sources which would cause more problems for
 them.
