2. Add persistency for grafana dashboards
When label monitoring_storage_class_name is specified dashboards altered using the grafana UI are now persisted if the pod is terminated. It is still recommended that the user utilizes a kubernetes configMap to persist the dashboard. task: 39514 story: 2006765 Depends-On: I42117837e8e3cd03f3cb723df4d73692ead0d169 Change-Id: Ieb90605182626869528349a7fdeed65061914bcb Signed-off-by: Diogo Guerra <diogo.filipe.tomas.guerra@cern.ch>
