Adding infra. for L1T object scaling constants from DB

[trtomei]

This PR adds initial infrastructure for the L1T-HLT interface for Phase2.
We add a new CondFormat for the L1TObjScalingConstants and a new DataRecord to hold that new format in a DB.

• We added it to the standard test:
  CondFormats/HLTObjects/test/testSerializationHLTObjects.cpp

and ran scram b runtests with success!

• We ran runTheMatrix.py -l limited -i all --ibeos with success.
