Kevin Fox 739646cff6 External Ceph Tools, Tests, and Docs
This PS does the following:
 * Add support for testing Cinder.
 * Fix tests for Nova/Neutron.
 * Add some Ceph more docs.
 * Add support for a second osd for testing.
 * Add a ceph-admin pod for easier Ceph admin related activities.
 * Add a ceph-rbd daemonset that that lets you use rbd with Kubernetes without
   needing to install Ceph on the host.
 * Add back missing Cinder Keystone endpoints.
 * Make storage provider filesystem type configurable.
 * Add a ton more logging to the gate job.
 * Support Ubuntu containers in the gate.
