Adding pre-selection to input (AK4) jets for tau RECO

This PR is replacement of #3594 by including changes on top of #3631
It adds the possibility to reject some jets as an input seeds for tau reconstruction based on their pt and eta. It is turned on by default and the requirements for running the tau RECO sequence are
1) pt > 14 GeV
2) |eta| < 2.5

The performance change is expected - loss of efficiency for very low pt true taus, and also decreased fake rate for very low pt jets.

However, no change is expected for the taus passing recommended kinematical cuts (pt > 20 GeV + |eta| < 2.3).

This is shown on slides: https://indico.cern.ch/event/316898/material/0/0.pdf

Additionally, one can expect improvement of overall timing needed for tauRECO (as the algorithm is executed fewer times) and also size reduction in the RECO PFTauCollection, as it will contain fewer candidates.

PR's #3558 and #3594 are being closed as they have been rendered moot by the #3631

@veelken and @monicava, this is something you wanted to watch as well
