/kind refactor

What this PR does / why we need it:

If uploading a token based kubeconfig, error reported as invalid kubeconfig.

In fact, token based kubeconfig is general usage in many cases.

@peter-wangxu Welcome! 👋 You are right, we are currently preparing to optimize certificate verification (such as #521 ) because it is not yet universal, so thank you for your PR, it's very useful!
But the unit test still needs to be adapted again, it failed :(

@peter-wangxu Thank you! If there is no problem after actual verification, we will merge it. Then we will release a small version, you can install to try it out.
