Description

In issues such as https://tracker.ceph.com/issues/23460, a deadlock can manifest as a completely stuck daemon. We should be dying in cases like this -- should use the HeartbeatMap class in ceph-mgr, same as we use it in the MDS and OSD.

Rook now has a mgr watcher to do exactly this. Wondering if we really need a solution on our own. Can we just rely on Rook here?
