[identity] keystone support for messaging

[Mark Vanderwiel]

here is the needed config

keystone.conf - depending on rabbit or qpid .... this example uses rabbit.

rabbit_host=
rabbit_port=
rabbit_use_ssl=
rabbitclient=
rabbit_password=
rabbit_virtual_host=

notification_driver=messaging
notification_topics=notifications
control_exchange=openstack

See https://github.com/openstack/keystone/blob/master/etc/keystone.conf.sample#L1289

Also need to change Common to add identity to the list of mq components here:
