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.

* `restuser` : Gluster REST service/Heketi user who has access to create volumes in the Gluster Trusted Pool.
* `restuserkey` : Gluster REST service/Heketi user's password which will be used for authentication to the REST server. This parameter is deprecated in favor of `secretNamespace` + `secretName`.
* `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".
When both `restuserkey` and `secretNamespace` + `secretName` is specified, the secret will be used.
* `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.
Example of a secret can be found in [glusterfs-provisioning-secret.yaml](glusterfs-provisioning-secret.yaml).
