Add foreach loop in script

Feature Requests
1

I think it would be useful to add foreach as a new type of loop to repeat, as it is not always easy/possible/nice to do it using repeat.index.

Additional related ideas:

  • Saving current value in repeat.value
  • Iterating over arrays created using jinja template
    (e.g. {{ state_attr('group.all_devices', 'entity_id') }})

My idea was to use it to call the same service with increasing delays between calls. There are a lot of potential uses :slight_smile:

A draft PR has been created. Still need to create tests and update docs.

Marked it as the solution, as it has been merged. Will be part of the 2022.5 release.
