Add support for latest puppetlabs-rabbitmq

This patch adds a new paramter to the rabbitmq class
that allows a user to specify the class name. This allows
selection of 'rabbitmq::server' - the old name, or 'rabbitmq' -
the new name changed during the recent rewrite of the
puppetlabs-rabbitmq module.

Fix file location for nova compute rbd secret

The rbd secret location was mixed between /etc/nova
and /etc/ceph. This patch changes the secret to
be in /etc/nova for both the file and exec
resources so that virsh secrets are set correctly
