For #11224 a79ad08

For Heavy Ions, adding E/p cut to electrons. #11223 is the 76X version of this PR, and it has already been approved by Reco.

The code changes are satisfactory, and Jenkins tests against baseline CMSSW_7_5_X_2015-09-09-2300 show no significant differences. A test for #11223 with workflow 140.53_RunHI2011 showed no significant differences, timing changes, or product size changes.

This pull request is fully signed and it will be integrated in one of the next CMSSW_7_5_X IBs once checked with relvals in the development release cycle of CMSSW (tests are also fine). This pull request requires discussion in the ORP meeting before it's merged. @davidlange6, @Degano, @smuzaffar

@davidlange6
was there a reason to not include this in 753?

[mandrenguyen]

@slava77 @davidlange6
This was the last requested addition to the HI reco.
It's a shame this wasn't included in 753. What's the timescale for the next 75X release?
