[master] Add option to transformation-debug to automatically exclude runs

This option allows to exclude from run checks those runs that are in status Unused, Problematic, Assigned, MaxResetin another transformation. This allows to check why runs are not flushed in merging productions, excluding runs that cannot be flushed because files are in the above statuses in the stripping production...

Example:

[localhost] ~ $ dirac-transformation-debug --Status Unused --Info flush 103804 --Except 103803
 Transformation 103804 (Active) of type Merge (plugin ByRunFileTypeSizeWithFlush, GroupSize: 5) in Real Data/Reco16/Stripping28r2
