Implement schedule filters

• I have searched the existing issues and didn't find my feature already requested there

Feature description

Schedules would receive the ability to filter run times returned from a trigger. If a filter rejects a run time, then the next fire time would be requested from the trigger, until a fire time is received that passes all the filters.

This function was previously served by AndTrigger, but it has proven to be very problematic in practice. There might be grounds for removal of AndTrigger if this feature is implemented.

Use case

A common use case for this is skipping holidays, as that requires special logic that would ordinarily require customizing a trigger.

As of 3.10.4 this was a bit of a pain-point, the documentation is wrong, the library will hang when i use this example because IntervalTrigger cant go with AndTrigger...

I should probably remove these examples. I haven't touched that part of the docs in a long time.

Please do, even better would be to add a note that it was removed because it doesnt work, that would have saved me a day :)
