storage_alerts: cluster label is optional

This commit make printing the `cluster` label in the storage alerts optional based on the label being present or not. If no `cluster` label is set, the phrase ` {{ with $labels.%(clusterLabel)s -}} on Cluster ` is left out of the alert description. Signed-off-by: Jan Fajerski <[email protected]>
