Add parameters for high pT particle protection in PUPPI

[ahinzmann]

PR description:

Add new parameter to PUPPI to deal with high pT particles. Recent studies have shown that the current handling of high momentum charged particles in PUPPI is suboptimal compared to CHS and a different configuration of PUPPI for Run3 is proposed.
https://indico.cern.ch/event/862332/contributions/3632864/
This PR implements the necessary switches without changing the current behavior of the algorithm, i.e. no changes to RECO+MiniAOD are expected from this PR.

At the same time the behavior of the parameter puppiNoLeptons, that is not used anywhere in CMSSW, is adapted such that implementation actually matches the name.

PR validation:

runtests

Backports

We would like to have these options backported to 10_6_X, to introduce a new PUPPI configuration for UL MiniAOD-v2 and for JMEcustomNanoAODs as soon as the PR is merged.

• A new parameterization is made available for puppi weights, as planned: justification for it is in the attached presentation, while a full large stat validation will follow.
• puppiNoLepton updated to better corresponds to its name
• Modified configs are not activated in the current workflows: no change in reco or miniAOD outputs onserved
• Jenkins tests pass

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 will now be reviewed by the release team before it's merged. @davidlange6, @slava77, @smuzaffar, @fabiocos (and backports should be raised in the release meeting by the corresponding L2)
