cinder rbd driver needs to check min config requirements

[Edward Hope-Morley]

The RBD driver should check that required configs are set on startup and fail to start if they are not. For example, rbd_user, rbd_pool and rbd_secret_uuid are all required when doing an attach if cephx is enabled. If they are not provided, a volume attach will silently fail (http://lists.ceph.com/pipermail/ceph-users-ceph.com/2013-June/002031.html) in nova-compute when it checks for those values and the volume will stay in the 'available' state providing no information to the caller about what went wrong.

This issue was fixed in the openstack/cinder 8.0.0.0b3 development milestone.

This was fixed in Mitaka, but I can't target the bug there any longer, so targeting it to Newton-1.
