   N.B., in order to use this class for mocking, every module we want to
   test with a mock GitilesRepository must not import that class directly.
   Instead they must import the gitiles_repository module and rely on
   dynamic dispatch to resolve the GitilesRepository attribute. Otherwise
   those modules will hold direct links to the real GitilesRepository
