Add differential pulls, and resolutions+pulls for PV to vertex validation

[makortel]

This PR updates the vertex validation in the following way

• Adjust "merge rate vs. closest vertex in z" x axis range to have uniform bin width when drawn with logarithmic x axis, and extend the minimum to 1e-4 cm
• Add pulls vs. number of tracks, PU, z, and sum(pT)
• Add resolution and pull plots for the PV
  • only for events where the reco PV is correctly identified
  • regardless if the PV is a merged vertex or not (to remind, for all vertices the plots are separate for non-merged and merged vertices)

Tested in 9_0_0_pre4, in addition of added histograms expecting changes in the merge rate vs. closest vertex in z histogram.

Thanks @makortel !
Is it going to also "solve" what we discussed about the x min of merged vtx for Phase2, right?

Yes (this is the first bullet of the description).

[ebrondol]

Exactly, great.

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