Enable filters in iterators (#15017)

Filters should not cut the whole workflow. These should only stop the
branch. This PR:
- adds a new skipped status 
- when a filter stops, it still goes to the next step
- the next step will execute if there is at least a successful step
- if only skipped step, it will be skipped as well

It allows to use filters in iterators.
