define a global set of qmtest exclusions for Rec

triggered by exclusions needed for the FunctorFactory which will be needed in Rec, Moore, and DaVinci.

This would define a new preprocessor similar to what is done in LHCbExclusions.py and I'd propose to then in Moore and DaVinci change lines like

from GaudiConf.QMTest.LHCbExclusions import preprocessor as LHCbPreprocessor

to

from RecConf.QMTest.exclusions import preprocessor as RecPreprocessor

to make them automatically pick up the new Rec exclusions.

wdyt @rmatev?
