Merged requested to merge fpastore/athena:CAmigratMaster into master
This MR is the first step to migrate the HLT Control Flow code (and the rest of the menu code) to use Component Accumulator. The core part of the changes is the ability to reuse the same menu generation code with and without CA (so in old and new configuration).
- added one test in TriggerMenuMT to test it: test_menu_CA
- modified CF component classes and their behaviour
- prepared makeHLTTree to be run in both configurations
