What this PR does?

We were getting error while loading dashboards json in grafana versions lower than 7.4.0
- Error: Template variables could not be initialized: e.replace is not a function

Reason for this error:

This was due to the nested query used over here.

"query": {
      "query": "label_values(openebs_size_of_volume,openebs_jiva_label)",
      "refId": "StandardVariableQuery"
    },

So instead of using a nested query, we can simply use an expression in a query.

"query": "label_values(openebs_size_of_volume{openebs_jiva_label=\"$openebs_jiva_label\", openebs_cstor_label=\"\"}, openebs_pv)"
