Description of problem (please be detailed as possible and provide log
snippests):

Currently  CephObjectStoreUser CRD  does not support adding role capability to a rados user. It only supports below caps:

users, buckets, usage, metadata and zone.

Doc : https://rook.io/docs/rook/v1.11/CRDs/Object-Storage/ceph-object-store-user-crd/#spec

Hence, on creating a user with role caps, got below error:

cat test-user-role-caps.yaml
~~~ 
apiVersion: ceph.rook.io/v1
kind: CephObjectStoreUser
metadata:
  name: test-3
  namespace: openshift-storage
spec:
  store: ocs-storagecluster-cephobjectstore
  displayName: test user
  capabilities:
    user: "*"
    bucket: "*"
    roles: "*"
~~~

~~~
oc create -f test-user-role-caps.yaml

~~~

This RFE is to implement role caps feature in rook.
