We can now connect an external prometheus exporter to Rook to collect
metrics and generate alerts from Prometheus.
Just enable this in the CephCluster CR:
```
spec:
external:
enable: true
monitoring:
enabled: true
rulesNamespace: rook-ceph
externalMgrEndpoints:
- ip: 192.168.39.182
```

Breaking Changes
Ceph
- rbd-mirror daemons that were deployed through the CephCluster CR won't be managed anymore as they have their own CRD now.
To transition, you can inject the new rbd mirror CR with the desired
countof daemons and delete the previously managed rbd mirror deployments manually. - old monitoring settings used in the
operator.yaml:ROOK_CEPH_STATUS_CHECK_INTERVAL,ROOK_MON_HEALTHCHECK_INTERVAL,ROOK_MON_OUT_TIMEOUTare now deprecated. Backward compatibility is maintained for existing deployments. These settings are now in theCephClusterCR, refer to health check section
