Update RHEL OS description, relies on Foreman #3720
BZ #1042933 - neutron-server fails to start

https://bugzilla.redhat.com/show_bug.cgi?id=1042933

Neutron-server fails to start when deploying Neutron controller host group via
Foreman.

This is due to a new neutron-db-manage command that needs to be run, but is not
yet included in puppet-neutron.  This patch mimics what was done in
packstack[1], fixing this until the proper fix is added to the puppet module we
depend on.

BZ #1043964 - Fix to move neutron setup after db setup.

https://bugzilla.redhat.com/show_bug.cgi?id=1043964

The 'neutron-db-manage upgrade' command was failing on first runs of puppet
agent due to a race condition where the database was not necessarily created
before this command was run.  The order matters, so we have now specified this
more precisely.
