During teardown, we sometimes have errors that processes are still running after being stopped, something like:
Fault: <Fault 91: 'STILL_RUNNING: TestTelegraf-0'>This is because we only retried slapos node report two times, but
slapos node report tells supervisor to stop processes without
waiting and when processes takes time to stop, this is sometimes not
enough. Increase to retry up to 10 times by default.
