Merged requested to merge amete/athena:master-atlasg-2496 into master
This is yet another follow-up to !61368 (merged). With this MR, each DAOD format now configures its own MetaData instead of doing this in the main skeleton (just like EventData but not quite as flexible yet, which needs a more modular
InfileMetaDataCfg but that's another story). It also fixes the bug reported w/ the
DAOD_TRUTHX production jobs.
