Unify MainServicesSerialCfg and MainServicesThreadedCfg
This MR unifies the MainServicesSerialCfg
and MainServicesThreadedCfg
methods into a single MainServicesCfg(ConfigFlags)
method. Config-flags decide if the job runs in MT mode or serial mode.
On top: Introduce a few new config-flags: Exec.MaxEvents
, Exec.SkipEvents
, Exec.OutputLevel
and Exec.DebugStage
.
