[TASK] SchedulerModuleController: Don't extend BaseScriptClass

To further phase out BaseScriptTask "SOBE", the scheduler
controller class no longer extends it and copies left over
usages to itself.

A general cleanup is applied along with this patch:
* Hard code some general variables like "moduleName"
* Remove some duplicate class attributes
* Additional namespace usages
