Problem/Motivation

(Almost?) All config entities have a machine name form field with an 'exists' callback that checks for an existing entity of that type with a given name. Each config entity has to implement such a callback even though it can easily be done in a generic fashion. What's worse: Even though the best practice is to perform these 'exists' check with an entity query many config entities simply defer this to the 'foo_load()' function which performs completely unnecessary loading. This already happens several times in core and will be even more widespread in contrib, I fear.

Proposed resolution

It seems this is a great use-case for a generic exists() method on the form controller. This only concerns config entities, though, so we need to create a new ConfigEntityForm.

Remaining tasks

  • Agree that this makes sense
  • Write patch
  • Review patch
  • Commit patch

API changes

No BC-breaks. There's a new ConfigEntityFormController that it's a best practice to extend.
