If the health spec of the CephCluster CRD has a timeout set to 0 like
so:
```
healthCheck:
daemonHealth:
mon:
disabled: false
interval: 45s
timeout: 0
```
And the mon goes out of quorum then Rook will not fail over the mon.
This is interesting when doing maintenance on a monitor and we don't
want to create a new one.
