kubeadm: always use a short timeout for clientset creation

Browse Source 
ToClientSet() in kubeconfig.go creates a clientset from
the passed Config object (kubeconfig). For IP addresses
that are not reachable e.g. Get() calls for ConfigMaps
can block for a few minutes with the default timeout.

Modify the timeout to a shorter value by passing an override.
