Using the default KUBECONFIG environment variable to indicate that
the Kubernetes tests should be run lead to cases where developers
accidentally ran the tests. This has now been changed to
"DEX_KUBECONFIG" and documentation hsa been added detailing how to
run these tests.
Additionally, no other storage reads environment variables for its
normal configuration (outside of tests) so the Kubernetes storage
no longer does.
Overall, be less surprising.
It's not clear that the best way to manage clients is through a
gRPC based command line tool. For example we may explore an admin
dashboard and enable bootstrapping through static clients.
For now use static clients while we hold off on a more concrete
proposal.
