> {{ActiveRepairService}} keeps a map `parentRepairSessions`. If these sessions leak, that map can grow to a size when a node restarts {{ActiveRepairService.onRestart()}} triggers a cleanup of sessions that can pause nodes in a cluster for a long time.
> The proposed solution is for repairs to cleanup these sessions on all nodes on completion.
