Re-introduce BeamSpotOnlineProducer for Phase-2 HLT menu

[mmusich]

PR description:

This PR proposes a somewhat alternative approach to deliver the online Beam Spot to the HLT menu in Phase-2 as the one introduced at #41047.
The goal is to re-align the Phase-2 HLT configuration to be the same as in Run3 (i.e. use BeamSpotOnlineProducer instead of BeamSpotProducer) this is achieved by means of:

• adding the hltOnlineBeamSpotESProducer (ESProducer for the arbitration) to the HLT menu itself;
• set useTransientRecord = True in the onlineBeamSpot configuration (in this way one do not need to use scalers input any longer);

As with the proposed configuration the BeamSpotOnlineProducer falls back into producing the in the event the content of the DB (BeamSpotObjectsRcd) this should not introduce any change in the HLT results.
One of the main objections to use BeamSpotOnlineProducer for the phase-2 setup was about the fact that it needs to consume BeamSpotOnlineCollection from the SCAL FED (which doesn't exist anymore in >= Run3). I therefore profit of this PR to change BeamSpotOnlineProducer in order to not consume it unless useTransientRecord is set to False. This and declaring this parameter as optional in the fillDescription method of BeamSpotOnlineProducer allows to avoid declaring hltScalersRawToDigi as input collection.

@beaucero @SohamBhattacharya , please have a look and let us know if you agree with this change to the Phase-2 HLT menu (cc: @fwyzard , as author of #41047).

[fwyzard]

@mmusich @missirol, what behaviour do we rely on for Run-3 ?

[mmusich]

what behaviour do we rely on for Run-3 ?

we use the same setup that is proposed here.

[SohamBhattacharya]

If there are no objections from TSG (e.g. @beaucero @SohamBhattacharya), I'll sign off for HLT by the end of the week.

Hi, this looks fine as far as Phase-2 HLT is concerned. Please go ahead.
Thanks!
