Erich Blume 2fae0f7161 C0: switch grafana deployment to Recreate strategy 
Grafana uses an RWO PVC for SQLite + Bleve search index. RollingUpdate
spawns the new pod before terminating the old one, so the new pod
crashloops on the index lock until rollout timeout. Recreate terminates
the old pod first, letting the new pod acquire the lock cleanly.

Switched Grafana's deployment strategy from RollingUpdate to Recreate. With an RWO PVC holding the SQLite database and Bleve search index, RollingUpdate reliably crashloops the new pod on the index lock until rollout timeout. Recreate terminates the old pod first so the new one acquires the lock cleanly.
