Access to LHC condition information

This MR is ready, just waiting for a local test on data

TO BE TESTED WITH Rec!3519 (merged), DaVinci!1017 (merged), !528 (merged) LHCb!4517 (merged)

First step towards Rec#497 (closed)

Access to LHC conditions by informing DeLHCb about LHCInfo properties. It allows to get from condition YAML files contained in https://gitlab.cern.ch/lhcb-conddb/lhcb-conditions-database/-/blob/master/Conditions/LHCb/Online/LHC.yml/ the following quantities

• FillNumber
• LHCState
• LHCEnergy
• LHCbClockPhase

Inspired by !383 (merged)!

TODO:

• Fix the test_DDS
