The current implementation of the Ceph CSI provisioner is tied too
closely with the older Ceph RBD provisioner, which doesn't let the
deployer deploy Ceph CSI provisioner without the old RBD provisioner.
This patchset will decouple them such that they can be deployed
independently from one another.
A few other changes are needed as well:
1) The deployment/gate scripts are updated so that the old RBD and
CSI RBD provisioners are separately enabled/disabled as needed.
The original RBD provisioner is now deprecated.
2) Ceph-mon chart is updated because it had some RBD storageclass
data in values.yaml that is not needed for ceph-mon deployment.
3) Fixed a couple of bugs in job-cephfs-client-key.yaml where RBD
parameters were being used instead of cephfs parameters.
