* Fix client regression from turbo mode refactor
The turbo mode refactoring introduced a regression where the kubernetes
client can fail to find the kubeconfig. This happens because
get_api_client is called twice and the second time it is called without
the module being passed as an argument. Without this, the configuration
will use defaults. This will be a problem if the user has specified a
location for the kubeconfig that's different from default, for example.
* Add tests
