Add OIDC authentication or error message about support authentication methods

I was trying to use the python client against a kubernetes cluster that uses OIDC authentication. The python-client tried to log in as an "anonymous" user, which failed. It would be good to add OIDC authentication or add an error message that the authentication method was not support.

kubernetes-client/python-base#31 is implementing this.

Thanks for the hint! I used the code from kubernetes-client/python-base#31 and found that there is a difference between how kubectl behaves and the python API. When a refresh token is necessary, kubectl does not require idp-certificate-authority-data to be set:

    if cfg[cfgCertificateAuthorityData] != "" {
        certAuthData, err = base64.StdEncoding.DecodeString(cfg[cfgCertificateAuthorityData])
        if err != nil {
            return nil, err
        }
    }

The error that is called seems to be suppressed somehow. Yet, with the same config the new oidc authentication requires idp-certificate-authority-data to be set:

ConfigException: Invalid kube-config file. Expected key idp-certificate-authority-data in kube-config/users[...]/user/auth-provider/config

There is a refresh-token URL provided in the config though, which might be what allows kubectl to get around the need for idp-certificate-authority-data

This issue is the same as #195

It appears this may be addressed via kubernetes-client/python-base#48; should this issue be closed?
