Integration with webform

I am pretty sure this integration has to be done via the Webform module.

There is ticket in the Webform module's issue queue for this request and this task has been added to the Webform module's backlog.

@maintainers Feel free to mark this as a duplicate issue.

Closing as "won't fix" because that's what happened to the issue in the Web form queue. It wasn't possible because webforms are config entities.
