heal: Fix heal sequences cleanup process (#6780)
heal: Fix heal sequences cleanup process (#6780)

The current code triggers a timeout to cleanup a heal seq from
healSeqMap, but we don't know if the user did or not launch a new
healing sequence with the same path.

Add endTime to healSequence struct and add a periodic heal-sequence
cleaner to remove heal sequences only if this latter is older than
10 minutes.
