TMSS-156: implemented TMSSBridge::getActiveSubTasks and TMSSBridge::getFinishingSubTasks as similar as possible for the moment as SAS/OTDB/sql/getTreeGroup_func.sql

TMSS-156: submit state changes to OTDB for id<2000000, and to TMSS for id>=2000000. Implemented same behaviour in _updatePlannedList for TMSS observations as for plain-old-otdb-observations

TMSS-156: use inverse boolean logic #ifndef DONT_COMPILE_OTDB_AND_PVSS_CODE, so that 'normal' MACScheduler behaviour with OTDB/PVSS is the default, and the devs have the oppotunity to disable OTDB/PVSS code actively by adding  -DDONT_COMPILE_OTDB_AND_PVSS_CODE=true to the cmake cmdline

TMSS-156: used #ifdef DO_COMPILE_OTDB_AND_PVSS_CODE everywhere, so that we have a compilable and runnable MACScheduler that polls TMSS

TMSS-156: copied business logic from otdb tasks for tmss tasks in _updatePlannedList. Use subtask['updated_at'] as modTime

TMSS-156: loopover upcoming subtasks, extract subtask_id, fetch parset, store parset on disk just as normal MACScheduler does, and send it on the bus. TODO: all the additional MAC bookkeeping

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
