Title: Strip cluster

Two Major component here:
1) Speed up of a factor two of the Strip Clusterizer
2) new infrastructure based on edmNew::DetSetVector for the OnDemand tracking
this version is fully backward compatible and support both old and new mechanisms
for reco and hlt.

This development has been discussed in depth within HLT/TSG, Tracker DPG and Tracking POG.
see
https://indico.cern.ch/event/301711/ (same slides the in Tracker POG)
and Mia's slide in https://indico.cern.ch/event/300088/

irrelevant regressions can be observed mostly due to changes in the calibration "accuracy" (double to float etc)

Once this PR will be in the release HLT will port the config to the new on demand mechanism.
in next (pre)-release cleanup of code will start.

It this therefore rather urgent to have an official pre-release incorporating this PR in order not to slow down the work on the HLT side
