[Bug] Leaked access-token on

[dturn]

Bug report

There was an error during a deployment that caused the kubeconfig.yml to be logged. The kubeconfig included an access-token. While access-tokens are short lived we shouldn't be logging them. Ideally we'd just sanitize sensitive information from the kubeconfig.yml instead of suppressing all of it. Possibly by not printing the auth-provider: section of a user or just not logging the entire users section

Error: Error loading config file "/app/config/kubeconfig.yml": v1.Config.Clusters:
[]v1.NamedCluster: v1.NamedCluster.Cluster: v1.Cluster.CertificateAuthorityData: decode base64: illegal base64 data at input byte 748, error found in #10 byte of ...|"}}]}|..., bigger context ...|"}}]}|...

Expected behavior:

access-token should never be logged.

Actual behavior:

access-token is logged as a part of the full kubeconfig.yml file.

Version(s) affected:

Likely all versions, but this happened on 1.0.0.pre.1

Steps to Reproduce

Unclear how to reproduce this exact failure. Might be enough to just have an invalid config file, but I haven't confirmed this
