Backend: Added a scheduler which allows to schedule the execution of functions
after a specified duration. The functions are keyed so execution can
be canceled before the actual execution.
This is useful for configurable schedules.
Futhermore this scheduler could be a building block to unify all regular
schedules in the gemma server.
