/kind feature

Why you need this feature:
Recently I had encounted a issue on our product that after loging to the Kubeflow, I got a 500 error, the menu can't show normally, looks like this:

And then I checked the centraldashboard pod log and got this,

After investigated I found it's due to the service account token life over 90 days, so the API had been rejected by AWS, refer here: https://docs.aws.amazon.com/eks/latest/userguide/service-accounts.html#identify-pods-using-stale-tokens

Describe the solution you'd like:
Restart the centraldashboard to refresh the sa token life.

Anything else you would like to add:
