rubin.gafaelfawr.gafaelfawr_dependency = <rubin.gafaelfawr._dependencies.GafaelfawrDependency object>

Maintain a global Gafaelfawr client.

This is structured as a dependency that creates and caches the client on first use to delay client creation until runtime so that the test suite has a chance to initialize environment variables.
