Small-R truth jets in DAOD_PHYS
This MR implements the following
(1) Changes in MCTruthCommon allow to add small-R jets in DAOD_PHYS. This was implemented by switching back to the old way of setting up things. The current implementation causes problems when scheduling jet reconstruction in different places. In the future we will switch to the new configuration hopefully everywhere
(2) Fix the MET_track container name in fJVT calculation
(3) Add calculation of event level cleaning variables
Item (1) makes @zmarshal happy hopefully :) Item (2) and (3) were reported in ATLPHYSVAL-671
