Watchers are lost on active RBD image with running client
The issue is observed on a Jewel cluster running with client 10.2.7 and cluster 10.2.10
Without a known reason watchers are lost on some images and this causes corruption/RO inside the running VM.
Restarting or a live-migrate of the Instance to a different node brings the Watcher back.
Creating this ticket here so it's tracked.
