Common Isolation & Selection Frameworks 72X Edition

#4685 + Code review comments and improvement of user interface.
Update of TWiki to come soon.

Also integrates code into MiniAOD, right now only electron IDs are embedded.

No ID code is run in the standard reconstruction at present.
We will need to talk to Validation/DQM about how to port the IDs that are used there into the framework.

Backports: 71X - #5015, 70X - #5014

This is what is meant by "Full5x5" in producer name, which is without the weights. If the energy weighting scheme changes it would be affect the nominal electron/photon sigma ieta ieta since the weighting is a direct result of the clustering.
