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

DB.

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.

Clarify no delayed delete on personal projects

See merge request gitlab-org/gitlab!47035

Previously it was not clear that delayed deletion of projects can
only be enabled for projects in groups, not for projects in personal
namespaces. This improves the documentation to reflect both aspects.

- There were no security issues with this, but this helps
make our FE more maintainable.
- Also adds spec for this component.
- Also updates QA selector view assertion.
