SW-699: Make notifications unconfigurable, greatly reducing complexity of the higher abstraction layers.

SW-699: Use a single broker and bus (exchange), and make service names unconfigurable (fixed in Service and RPC). Greatly reduces configuration size.

SW-657: changed rpc timeouts to sane values, so scheduling does not hang on long-term blocking rpc calls

LSRT-16: log exceptions in scheduling. When the Dwell/Priority schedulers cannot allocated the required resources, then try again with basic scheduler to end up with a situation with the 'normal' conflicting resources, which can then be evaluated by users

Task #9893: Now using radb.get_overlapping_claims() instead of the non-existing radb.get_conflicting_overlapping_claims()

Task #9893: Some refactoring to make possible that a task already on 'conflict' after scheduling is not put on 'conflict' again, but does result in a message on the notification bus.

Task #9893: Altered the conversion between (starttime, endtime, min_starttime, max_endtime) into the (min_starttime, max_starttime, duration) required by the DwellScheduler

Task #9893: RA now also puts notification message on bus in case of task in conflict state. Unit tests all working again. Dwelling functionality enabled in RA.
