Currently if multiple instances of the ceph-client chart are deployed in the same Kubernetes cluster, the releases will conflict because the clusterrole-checkdns ClusterRole is a global resources and has a hard-coded name. This change scopes the ClusterRole name by release name to address this. Change-Id: I17d04720ca301f643f6fb9cf5a9b2eec965ef537
