Add efficiency and fake rate vs. dxy/dz wrt PV to MultiTrackValidator, and make normalization+cumulative histograms before efficiency in DQMGenericClient

[makortel]

This PR adds the following histograms to MultiTrackValidator (only to the Tracks instance): efficiency and fake/duplicate/pileup rates vs.

• dxy and dz wrt. primary vertex
• cut on dz wrt. primary vertex in couple of flavours
  • cut on dz(PV)
  • cut on dz(PV)/zError
  • cut on dz(PV) weighted by TP/track pT
  • cut on dz(PV)/zError weighted by TP/track pT

All of these are filled only for events where the reco PV (offlinePrimaryVertices[0]) is matched to the simulated PV (of the signal event). These plots help to understand and monitor the association of tracks to the PV.

In order to make the "efficiency/rates vs. cut on dz(PV)" plots, I moved the normalization and cumulation in DQMGenericClient to be done before efficiency calculation. This change has no effect on the current users of the cumulation feature.

Tested in CMSSW_7_6_X_2015-07-25-2300, no changes expected in existing histograms.

This pull request is fully signed and it will be integrated in one of the next CMSSW_7_6_X IBs (tests are also fine). This pull request requires discussion in the ORP meeting before it's merged. @davidlange6, @Degano, @smuzaffar
