Merged requested to merge ibragimo/athena:dev/reimpl-mva-assessment into 22.0
This is a duplication of the !55330 (closed) (already approved) closed because of a mistake during manual squash (rebased to master instead of 22.0). Copying the description here:
This MR replaces the old way of assessment of mva histograms in the online post-processing, since it wasn't working. The changes, summarised below, are only relevant for the online (Global) monitoring, i.e. Tier0 processing remains untouched.
- 1D mva live histograms per module (per fe for IBL) are created (the values for filling are already cached)
- those histograms are read by post-processing machinery and grouped per layer using appropriate filters
- per-layer assessment is performed, output FixMe histograms showing bad (=1) or good(=0) status of modules are created.
