Drop Commissioning helpers DaqSource based.

These does not work anymore since #814 and related bits that remove DaqSource. I remove it for now. I you want to have it back:

```
git cms-addpkg IORawData/CSCCommissioning
git cms-addpkg IORawData/DTCommissioning
git revert f44cba3
git revert 2fd1b25
```
