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

Task #10079: manually copied parts of the QA package into LOFAR-Release-3_1. This allows us to roll out a new LOFAR-Release-3_1 on the scu with an extra QA_Service. The QA_Service hardly depends on anything, and doesn't require modifications to the rest of the lofar code. This makes this unusual manual merge acceptable. The rest of the QA code is not part of this release, and is not merged to this branch (yet). It runs isolated in docker containers on cep4.

Task #11406: Accepted new output for integration tests working on flagged data. Removed deprecated 2nd FFT in tFlysEye test.

Task #5441: COBALT RSP raw support: add integration test tRSPRaw. Output verification depends (now compile-time) on printRSP.

Task #5441: COBALT RSP raw support: address Jan David's reviewing comments, implement RSP raw output parset value patching, and more

Add timestamps to echo lines at messagebus create/delete queue and to COBALT testFuncs error(), so we can further analyze the flickering tstartBGL test

Task #9989: SubSystems Dragnet: replace building StorageQueryService by ResourceTool (supplements r37695). Also build XML_generator.

Task #10898: Add QPIDInfrastructure to rollout on scuXXX to allow the service infra to be editted off the bat

Task #9893: Fixed test after merge: do not need lofarinit.sh (or make install) for Cobalt integration tests anymore

Task #9939: fix and extend tstartBGL test. Also reduce sub-test timeout from 30s to 20s to keep total max timeout the same. Supplements r37508. Test now passes on cbm009 and covers the DRAGNET case in cobalt_functions.sh.

Task #10690: Use a fixed directory for $LOFARROOT/etc/parset-additions.d/override, and thus also removing it from the installation

Task #8691: Cobalt: add cap_sys_resource to list of capabilities. Used for setrlimit if we don't have cap_sys_admin.
