AthenaMonitoringKernel: always set kAlwaysCreate for lumiblock histograms online (!64149) · Merge requests · atlas / athena

Frank Winklmeier requested to merge fwinkl/athena:klbn into 23.0 Jul 05, 2023

For the correct functioning of the Gatherer, lumiblock histograms should always be created with the kAlwaysCreate option to ensure they are re-booked on each LB change.

Relates to ADHI-4947.

P.S.: Should have really done this a long time ago. I was reminded by @stelzer in !64147 (merged).
