hAdd a rule to enforce resolver type annotations

See merge request gitlab-org/gitlab!47375

This new rubocop rule enforces that all resolvers declare their type.

This is important for several reasons:

- developers can read a resolver and know what it does, by understanding
  what it is meant to return.
- we can enable better testing of resolvers, by creating fields from
  resolvers using `Resolver.field_options`.
- Resolvers become the SSOT for field metadata, enabling us to eliminate
  repetition and boilerplate.

Add FF to avoid directly accessing diffs via gitaly

Guard against existence of project_features.requirement_access_level

See merge request gitlab-org/gitlab!47458

Having a hardcoded ID means this spec would fail when there are
preceding specs that already created a design. We roll back and clear
the DB after specs are run but the sequence isn't reset so we cannot
guarantee the IDs for the designs created in this spec.
