> Many of the housekeeping/background tasks can be turned off in case of having
> multiple instances running parallel.
> Some are controlled via the housekeeping node configuration, others are not
> started if their frequency is set to zero.
> The DB-Notification cleaner unfortunately doesn't have this functionality
> which makes all instances to race for the lock on the backend HMS database.
> Goal is to add change to be able to turn cleaner off in case if there are
> multiple instances running (be able to bound it to the housekeeping
> instance).
