Prepare for changes in Gaudi v40
- gaudi/Gaudi!993 (merged) replaced 2 "normal" warning messages with one info message in EventLoopMgr and HiveSlimEventLoopMgr.
- gaudi/Gaudi!1632 (merged) remove support for legacy GeudiExamples test helpers (renamed as GaudiTestSuite)
- gaudi/Gaudi!1756 (merged) remove support for anonymous Property instances
- gaudi/Gaudi!1764 (merged) drop compatibility with Gaudi v20 IInterface
I also removed a reference file that was not used because of the wrong naming convention (it is not used and the tests are not failing, ergo is not needed).
