GT update for MVA and HCAL
update of the trigger paths with monitor for Hgg and Htautau and H+
Add edm::ConsumesCollector to constructors of PixelTrackFilter classes

Needed because HIPixelTrackFilter and HIProtoTrackFilter (both derive
from PixelTrackFilter) read from edm::Event.
Migrate HIProtoTrackFilter and HIPixelTrackFilter to getByToken
introduce a mode to run EmDQM without automatic configuration of the paths but from a python config file
Added 50ns GT
Made MagGeometry thread safe

Changed MagGeometry to use an std::atomic<> for its cache of the last volume used. This will allow thread-safe comparisions.
Changed const member functions to return const pointers to member data. This is also needed for thread-safety and was
caught by the static analyzer.
Also changed member data which were pointers to be const pointers in order to help  make future maintanence thread-safe.
