Load client-auth plugins

[ripta]

Without this change, for example, kops connections using OIDC to the cluster will receive this error message:

cannot build kube client for "$CLUSTER_NAME": No Auth Provider found
for name "oidc"

kubernetes/client-go#345 suggests importing the package path plugin/pkg/client/auth/oidc from client-go. However, looking at the code at plugin/pkg/client/auth, it will actually handle loading all known auth plugins for us.

This is the first time I've touched BUILD.bazel, so let me know if I missed anything. That said, make version-dist completes successfully and this change made OIDC auth work correctly.

Whoops, left off the @.

Hi @ripta, in order to get this to pass you'll need to reorder your insert in BUILD.bazel. Please checkout the failed test.

If you run make bazel-gazelle this should be automatically fixed for you. Then amend your commit with git commit --amend. Let us know if you need more help!

@mikesplain - Thanks for the pointer. I amended my commit. I'll retest and check back.
