Added skeleton for FTAG ART tests with dcube plot monitoring

Introducing first skeleton for FTAG ART tests running AOD -> DAOD_PHYSVAL -> NTUP_PHYSVAL + dcube plot monitoring, following example of existing https://gitlab.cern.ch/atlas/athena/-/tree/main/Tools/CampaignsARTTests as suggested in https://indico.cern.ch/event/1285360/contributions/5401207/attachments/2658653/4604986/CampaignARTTests_UpgradePlenary_final.pdf

This is a first basis, to be refined subsequently by FTAG experts with list of dcube plots to be tailored according to the needs.

The outputs obtained with this config can be checked here
