Reloading is a heavy-weight operation, and currently it is not
possible to stop an orchestrator from spamming reload requests.
Add configuration options to allow rate-limiting.
Let's keep the debug logs in the journal, while logging only
testsute-*.sh stdout/stderr to the console (ba7abf7). This should make
the test output log a bit more readable and potentially the tests itself
a bit faster by avoiding console oversaturation.
Also, it should significantly reduce the size of artifacts kept by CIs.
Cover the case where a service is recovered out of reloading state via
a restart Restart= configuration.
