Create descriptive TaskScheduler Framework

[Legion2]

Create a Framework for the TaskScheduler using annotations to describe interval schedules and time triggered schedules. The annotated time triggered schedules can be activated using the api of the TaskScheduler. The interval schedules are scheduled automatically with the start of the Application.

This Framework ensures that Service references MUST NOT be passed to the TaskScheduler to have access to them in the scheduled runnable.
This is currently the case!

Deprecate the current programmatic TaskScheduler api.
