Adding K0s Qc to GLO matching QC, and move to a different location

[chiarazampolli]

This PR adds a first inv mass plot from K0s to the GLO matching QC (added here to not add another QC). The use of this is regulated by a flag. To resolve issues with dependencies, the GLOQC was moved to a separate directory. @mfaggin , @iouribelikov , @f3sch , @alcaliva , @noferini , @shahor02 See also: https://its.cern.ch/jira/browse/QC-1174
