Is your feature request related to a problem?

I'd like to see a feature in the UI for updating nodes of the cluster.

Describe the solution you'd like

Ideal behavior would be

1. Maintenance Mode one of the nodes
2. Evacuate running VMs off the node if a reboot is necessary
3. Put CEPH into MM (noout etc)
4. Apply patches to that one node
5. Reboot that one node if necessary
6. Remove Node from MM
7. Remove CEPH MM Flags
8. move onto next node in cluster if applicable

Have you seen this feature anywhere else?

Ideally a rolling update to minimize downtime.

Describe alternatives you've considered

Attempting to do with ansible as well, but do not have a test cluster to test on.
