For #10580 8c920bc

For Tracking, factorizing PreSplitting configuration from the InitialStep. This code improvement to facilitate tuning should have no effect on monitored quantities.

The code changes are satisfactory, and Jenkins tests against baseline CMSSW_7_6_X_2015-08-07-1100 show no significant differences, as expected. A check of the expanded RECO config of workflow 25202.0 confirms the new pre-splitting is included.

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
