Add the efficiency estimation to common FF task.

Add the efficiency estimation to common FF task.

This part contains the following modifications:
- 2 lists containing the AOD MC tracks and AOD rec tracks after quality cuts,
but without any pt/eta cut
-  a jet list for pointing into the generated tracks (this could be generated
or reconstructed jets)
- the QA histos for these jets (not strictly speaking 100% necessary if one is
interested in efficiency only, but useful for crosschecks).
- 2 THnSparse histos for single track efficiency and jet track efficiency
