Unused private data member.

The `ZdcCablingSvc` (intended as a wrapper to the `ZdcCablingService`
singleton) is not used anywhere in Athena and no component is actually
being built in this package. So delete this code entirely.

Delete the obsolete `Reconstruction/RecExample/RecExCommission` package.
Also delete files in other packages that are related and obsolete. The
`rec.Commissioning` flag remains as that seems to be set to `True` in
various places. Even for those cases, there should be no change in job
configuration.

Move only remaining `MinimalCommissioningSetup.py` to RecExCond package.
