Install neutron components on Zun compute hosts without Nova
Install neutron components on Zun compute hosts without Nova

At present Zun will only work on hosts with Nova present as these
receive the relevant Neutron components. This patch adds the
Neutron components to the Zun compute group so they can be
installed in environments where Nova and Zun are kept separate.
