be able to customize openshift auth timeouts

Customer has a condition where their cluster's API server is not responding to Kiali's authentication requests within Kiali's hardcoded 10 seconds.

We need to make the timeout configurable. We also want to make the OAuthClient token duration settings (inactivity and max age) configurable too.

Github enhancement request: https://github.com/kiali/kiali/issues/5650
