CAPEDWARF-139 Rewrite logging into separate cache
CAPEDWARF-142 Log lines returned by LogService are not returned in the same order they were logged in
Add tests if LogQuery.startTimeMillis and endTimeMillis are honored
CAPEDWARF-143 LogQuery.startTimeMillis should not have any effect on what log lines are returned
Add explicit test to check if LogQuery.minLogLevel has any effect on what AppLogLines are returned (it shouldn't)
Use Application for appId.
