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

SW-402: merged ltastorageoverview from trunk into LOFAR-Release-3_1 for deployment to production as per request by SOS/SDOS

SW-283: start IngestEventHandler with configurable and proper default options in scraper, so that the scraper will automatically visit the recent additions from ingest.

Task #8721: SW-280: processed review comment: added some tests for the scraper Location class. made some minor changes to the scraper module. Not going to do a full refactoring; I agree some methods in scraper.py are too big, but they are self contained and not part of a public API. So it's good enough for now.

Task #8721: added bin files, changed paths for python modules into lofar/lta, added supervisor ini files

Task #8721: faster inserts of lists of subdirectories. Better handling of srmls faults; reschedule failed srmls calls/parses
