TMSS-156: made proof-of-concept where TMSSBridge can query for and parse upcoming subtasks, and request a parset. Needs to be further implemented in _updatePlannedList

TMSS-156: use hostname, port, user and pass from configuration file. TODO: replace test user/pass with secret user/pass which is not stored in git

Task #11384: Increased ObservationControl timer for sending FINISHED/ABORTED from 10s to 300s to allow more time for FeedbackService to put feedback in OTDB before MoM retrieves it.

Task #9634: removed some of the needed logging to solve the issue. I left the logging of starttime per observation on, which helps a lot to see what macscheduler is doing

Task #9607: added logging in MACScheduler::_updatePlannedList() to identify if the missed observations are due to a potential race-condiction in itsOTDBconnection->getTreeGroup and the timeBeforeStart check

Task #9487: Do not override already set itsQuitReason, and explain EMERGENCY_TIMEOUT when reporting the error

Task #8531: Added unittest for TreeStatusEvent daemon and updated MACScheduler to new getTreeGroup function.

Task #8065: Do not abort if 0 stations are left. Keep aborting when OnlineControl/PythonControl are gone though.
