This commit applies the filtering imposed by LogLevelMax on a unit's processes to messages logged by PID1 about the unit as well. The target use case for this feature is a service that runs on a timer many times an hour, where the system administrator decides that writing a generic success message to the journal every few minutes or seconds adds no diagnostic value and isn't worth the clutter or disk I/O.
