Nice to have: Being able to define a maximum tree depth

For tree like collections, it would be helpful to define a maximum depth for editors, directly on the model.

Use case:
Eg:
query AllPagesSlug($locale: SiteLocale) { allPages(locale: $locale) { id slug parent { slug parent { slug parent { slug parent { slug } } } } }

If the editor goes beyond that depth (5), this query will not work as intended.
