[Phase-2] Validation of Phase-2 HLT paths and high level objects

[SohamBhattacharya]

Currently there is no proper DQM for the Phase-2 HLT paths and high level objects (objects that are used to build the paths -- leptons, jets, etc.).
A tool (developed by @Sam-Harper and @finnlabe) already exists in CMSSW to do so. This has been used privately by some POGs, but not used centrally, afaik.
However, the tool should be hooked to jenkins so that it can be triggered for Phase-2 HLT workflows.
That will help us monitor the impact of any PR can potentially impact Phase-2 HLT.

The first step would be to have a config for the aforementioned tool with the Phase-2 HLT paths, for which I will be opening a PR very soon.
I am raising this issue to discuss how to best proceed after that.

With #44776 almost ready, we should move towards adding this to regular release validation configurations (as @mmusich also commented).
I can take a look at doing so, but I'll need some pointers as to which configurations need to be changed.

N.B. @Sam-Harper is working on a few fixes to the tool -- eta for that PR is end of the week.

• PR HLT Gen Validation #47252 introduced the necessary validation modules to perform HLT paths and high level object validation against GEN-level information.
• PR Add GEN-level HLT validation to standard validation sequences #48327 (merged in CMSSW_15_1_0_pre4) ported the configuration of the modules and sequences introduced in HLT Gen Validation #47252 to the regular HLT validation sequences for phase-2.
• resulting plots are available for users in the CMSSW_15_1_0_pre4 relvals, see e.g. here
