Looks like they changed the definition of the health check service and we need to fix our mock in the tests:

Error: runtime/mux_test.go:759:59: cannot use &dummyHealthCheckClient{…} (value of type *dummyHealthCheckClient) as grpc_health_v1.HealthClient value in argument to runtime.WithHealthzEndpoint: *dummyHealthCheckClient does not implement grpc_health_v1.HealthClient (missing method List)
