GraphQL support for Notes created in discussions62826-graphql-note-mutations
A new `discussion_id` argument on the `createNote` mutation allows people to create a note within that discussion. The ability to lazy-load Discussions has been added, so GraphQL.object_from_id can treat Discussions the same as AR objects and batch load them. https://gitlab.com/gitlab-org/gitlab-ce/issues/62826 https://gitlab.com/gitlab-org/gitlab-ee/issues/9489
