With support of http, https, and socks5 proxy support. We already
support configuring this via environmnet variables, but this approach
becomes inconvenient dealing with multiple clusters on different
networks, that require different proxies to connect to. Most solutions
require wrapping clients (like kubectl) in bash scripts.

The usecase of this change:
When a super user grant some RBAC permissions to a group, he can use
--as-group to test whether the group get the permissions.
Note that now we support as-groups, as-user-extra in kubeconfig file
after this change.

Change validateClusterInfo to use clientcmdapi.NewCluster() instead of
clientcmdapi.Cluster{} when comparing against the passed in clusterInfo.
clusterInfo most likely will be a combination of
clientcmdapi.NewCluster() merged with potential overrides. This is
necessary because otherwise, the DeepEqual between what is supposed to
be an empty Cluster and clusterInfo will fail, resulting in an error
that doesn't allow fall-through to checking for in-cluster
configuration.
