Add functors to retrieve LHC conditions

GOES WITH Detector!418 (merged), DaVinci!1017 (merged) LHCb!4517 (merged)

Second step towards #497 (closed)

Add the following functors to retrieve LHC condition information from parent algorithm:

• CONDITION: general functor to access to condition derivation from DeLHCb
• LHC_INFO: set of LHC condition from yaml files in https://gitlab.cern.ch/lhcb-conddb/lhcb-conditions-database/-/blob/master/Conditions/LHCb/Online/LHC.yml
• FILL_NUMBER, LHC_ENERGY, LHCB_CLOCKPHASE: LHC conditions derived

TODO:

• Fix CONDITION functor
• Add tests on DaVinci
