Necessary code changes to allow for the use of DD4HEP with FT.
Related to Phys!1003 (merged), Allen!698 (merged), Boole!364 (merged), Rec!2562 (merged) and LHCb!3264 (merged)
Based on top of !126 (merged)
Current issues:
- Some FIXME's are left to signal potential sources of errors
In DD4HEP:
- Gaudi failures: (Multi)DiGraph has no attribute 'node'
- LHCb: 6 failures, maybe actually OK (they are in the DB loading so it makes sense they should be different)
- Rec: ERROR Cannot retrieve /Event/IOVLockDD4hep from transient store
- Moore: only saw issues with missing countermerger
- Boole: only saw
no valid data at /dd/.../FT. Do not know what it means
