[TrigSteerMonitor+TrigValTools] Implement per-chain express stream rate and counts monitoring
Implement feature request ATR-26047 to allow monitoring per-chain express stream accept rates at P1.
- Add an extra row in
TrigSignatureMoni
histograms for chain counts and rates, representing the express stream accepts of a given chain. The finalize() table printout is also updated with an additional column representing express. -
chainDump.py
is adapted to correctly parse the updated histograms as well as produce a new output fileHLTExpress.txt
listing the express accept counts for each chain.
