The following Merge Requests are included:

* MR 544: RRC Inactivity Timer testing
* MR 581: Remove deprecated build options
* MR 583: RRC: add an option to enable measurement reports
* MR 590: bugfix UE realtime bug

  -- scenarios were using FDD 5MHz conf file w/ active RRC inactivity timeout
  -- since we are waiting very long that UE is sync'ed w/ eNB, timeout occurs and UE is released
  -- solution is to disable timeouts in command line in scenario
  -- also python is fixed to handle properly wrong ping exits
