endpoint is missing as part of ClusterRole rule. This in turn throws …

…a error when gluster-block pod is provisioned.

So, add ClusterRole to perform read/write with endpoint.

Note: endpoint is added in glusterblock-provisioner as part of
the PR: kubernetes-retired/external-storage#957

Fixes: https://bugzilla.redhat.com/show_bug.cgi?id=1723366
