Description of problem: According to the Ceph documentation at http://docs.ceph.com/docs/master/rbd/rbd-openstack/ there are some additional Nova options we should be setting when using Ceph as the backend. I don't see any references to these params in our templates, so they were probably just missed in the initial Ceph implementation.
Two in particular that were noticed when documenting external Ceph are:
It doesn't seem that either of these are required for Ceph to function as the Nova backend, but it may be performing suboptimally when they're not set correctly.
This bug did not make the OSP 8.0 release. It is being deferred to OSP 10.
Moving into POST as this was merged upstream
verified on puppet-tripleo-5.2.0-1.el7ost.noarch
