Draft: IOVDbSvcConfig: Add DelayedConditionsCleanerSvc
A second attempt of DelayedConditionsCleanerSvc configuration after !56094 (merged). It seems a flag sync was missing to make it work reliably in wrapped jobs.
I tested the failing trigger test locally and I confirm this fixes ATR-26233 (but then the test crashes somewhere else for me).
Running with full-unit-tests this time.
