Introduce OnlinePopCon mechanism

[francescobrivio]

PR description:

This PR introduces a new OnlinePopCon mechanism that will serve the O2Os aiming at writing lumi-based IOVs for HLT.
The implementation is following the same structure of the already existing PopCon mechanism:

• PopCon --> DB upload through PoolDBOutputService
• OnlinePopCon --> DB upload through OnlineDBOutputService

and it is largely borrowed from the PopCon code itself, with the appropriate/minimal changes required for running the OnlineDBOutputService.

The first and only (for now) customer of this mechanism are the LHCInfoPerLS and LHCInfoPerFill O2O, when run in "duringFill mode".

Opening as draft since there are still a few open points to address:

• Understand if m_dbService->forceInit(); (copied from PopCon) is needed also in OnlinePopCon
• Add a unit-test
• Confirm all the needed methods are present

PR Validation

Code compiles, but no other specific validation is done for now.

Backport:

Not a backport.
A backport for the 2024 data-taking release will be opened once we converge on this PR.

I believe the relval failures are unrelated (failing in other recent PRs as well)

This pull request is fully signed and it will be integrated in one of the next master IBs (but tests are reportedly failing). This pull request will now be reviewed by the release team before it's merged. @sextonkennedy, @antoniovilela, @rappoccio, @mandrenguyen (and backports should be raised in the release meeting by the corresponding L2)
