Draft: Created a new compliance frameworks service for use with GraphQL endpoints

What does this MR do?

This MR adds a new compliance frameworks service to handle the retrieval and submission of compliance frameworks data via our GraphQL endpoints.

The service handles the normalising and return of errors as well.

This will be used by the compliance frameworks form, as well as more generally anywhere else where compliance frameworks are needed via GraphQL.

Screenshots (strongly suggested)
