Cosmic muon validation

[abbiendi]

This PR adds a complete validation of muon tracks for cosmics reco plus a few fixes to the general muon validation.

For cosmics an equivalent code has been used to obtain the validation plots attached to the PR #7044 #7044

The cosmics validation sequence could be used to implement a standard validation on cosmics processes in runTheMatrix (7.0, 1307.0 - this is left open)

Backport to 74X (straightforward) should follow this PR

Some details:

• for cosmics validation some changes to common tools with TRK are necessary. This does not break anything as currently there is no validation for cosmics in CMSSW.
• some fixes to muon validation has been added:
• validation plots of reco quantities only for signal-matched muons (useful to remove contamination from PU to the interesting quantities, and to validate samples produced with premixing)
• technical improvements (still only a first set, more to come) reducing the cpu footprint of muon validation
• fix the indentation in MuonTrackValidator (broken since 620 !)
• minor fixes to log messages

This pull request is fully signed and it will be integrated in one of the next CMSSW_7_5_X IBs unless changes (tests are also fine). This pull request requires discussion in the ORP meeting before it's merged. @davidlange6, @nclopezo, @ktf, @smuzaffar
