7x add reco geometry tag production info

Add production tag info in reco geometry file in order to know which detector elements to draw in projected and 3D views.
To choose Run 2 geometry correctly this should be:
```
process.GlobalTag.globaltag = autoCond['run2_mc']
process.load("Configuration.StandardSequences.GeometryDB_cff")
process.load("Configuration.StandardSequences.Reconstruction_cff")
```
