Overlay: Copy TrackRecordCollection and CaloCalibrationHitContainer (ATLASSIM-3911, ATLASSIM-3917)
Copy TrackRecordCollection and CaloCalibrationHitContainer from one StoreGate to another. Uses file peeking to determine which containers need to be copied over.
Also data overlay now uses common metadata code.
Note: I use non-standard CfgGetter syntax but we will migrate to the new configuration at some point anyway.
