SW-310: Added a docker template lofar-test to build a docker that can build the lofar code and run the various ctest tests.

SW-552: added module tbb_caltables.py which enables us to add (processed/converted) calibration information to the tbb spectral files

SW-567: added and used TaskInfoCache for fast lookup of info needed to accept/reject tbb alert voevents. The TaskInfoCache preloads all current information upon start, and then resfreshes itself on task status events, so it's always up to date.

Task SW-560: Added executables to operate tbb via tbbservice, refined recipe according to discussion with Sander

Task SW-559: provide interfaces for decider and event listener implementations, general layout of the decision-making and integration in the triggerservice.

SW-540: moved ssh_cmd_list method into seperate module ssh_utils.py. Added module lcu_utils.py with wrappers around lcurun and the stations.txt file and fetching station calibration tables.
