configure HLT precision electrons step in newJO

Tomasz Bold requested to merge tbold/athena:add-ele-recision-step into master

This MR adds electron precision step in HLT newJO test. Changes were necessary in offline egamma components that were used. Not everything worked so I added necessary configuration where needed. In particular whole cluster correction setup simply does not work. I hope we can rework it to be more aligned with the newJO style because the one that is inspired by rec-ex-common seems unnecessarily convoluted (presumably for historical reasons) Extrapolator setup is not exactly identical as in rec-ex-common setup. And last but not least, for the few events that we run the precision selection always fails so the chains give 0 counts now.

Followup actions:

  • sync. extrapolator setup
  • expand (and decide) on egamma clusters corrections
  • add more advanced chains using the ML selections
  • need also to sync fast calo settings because now the lhvloose chain fails in this step
