Removing muon quality variable from PHYSLITE
Following the discussion in https://its.cern.ch/jira/browse/ATLASG-2544 , it seems that muon quality as written directly is not something that should be used for analysis. If that's the case, then I (personally) find it more clear to remove the variable to make it obvious that it cannot be used.
Just offering an option here to make clear that this is a (straightforward) technical option.
This shouldn't get merged without some comment from @mvanadia , @hrussell , @gwatts , @egramsta (or some combination of them), but not marking as draft so that the CI goes ahead and runs.
