Setup rabbit user/pass for keystone

It is defaulting to guest/guest, and we are removing
the guest user in rabbit. So we need to create the user
in rabbit as we do for other services as well.

Please see: https://git.openstack.org/cgit/openstack/puppet-keystone/tree/manifests/init.pp?h=stable/kilo#n177
