test(api/gitlab/v1): add token auth utility functions to api test
Related to #960 (closed) & #976 (moved)
Context
Introduces the test functions for generating and configuring JWT token authorization (as opposed to no-authorization or "silly" authorization) in the api integration test suite.
This will be useful in writing/modifying (existing) tests for #960 (closed) where a JWT with an access.meta.project_path
claim is required to successfully access the rename-repository endpoint (discussed in #976 (moved))
