This is a first step in trying to incorporate the trigger configuration into the offline configuration (ATR-20389).
- Added a flag on the trigger side so we can configure properties of offline algorithms and tools differently in trigger jobs (this was changed in both instances of MuonSliceFlags. We use only the version in TriggerMenu at the moment, but will eventually switch to the other version, so keeping both up to date)
- Set the properties for the segment finding that need to be different for the trigger according to the added flag
- Reorganised slightly the MuonStandAlone.py configuration so that we can import directly the algorithm configuration from the trigger jobs
- Updated MuonSetup to use the configuration directly from the offline configuration (with the newly added flag set to true)
