Merge pull request #36437 from humblec/glusterfs-clusterid-prov
Automatic merge from submit-queue Add `clusterid`, an optional parameter to storageclass. At present, admin doesn't have the privilege to chose the trusted storage pool from which persistent gluster volume has to be provided. This patch introduce a new storage class parameter which allows the admin to specify storage pool/cluster if required. Signed-off-by: Humble Chirammal <hchiramm@redhat.com>

* `secretNamespace` + `secretName` : Identification of Secret instance that containes user password to use when talking to Gluster REST service. These parameters are optional, empty password will be used when both `secretNamespace` and `secretName` are omitted. The provided secret must have type "kubernetes.io/glusterfs".

* `clusterid`: `630372ccdc720a92c681fb928f27b53f` is the ID of the cluster which will be used by Heketi when provisioning the volume. It can also be a list of clusterids, for ex:

"8452344e2becec931ece4e33c4674e4e,42982310de6c63381718ccfa6d8cf397". This is an optional parameter.
