Add support for the bind RBAC verb

[raesene]

What would you like to be added

At the moment the bind verb which is available on Kubernetes clsuter roles does not appear to be supported

kubectl-who-can bind clusterroles
Error: resolving resource: the "clusterroles" resource does not support the "bind" verb, only [create delete deletecollection get list patch update watch]

If would be good if bind was factored into the tool. Similarly to escalate, it would be good to add support for the verb in general, but also to indicate it as another path for privilege escalation.

Why is this needed

The bind verb allows principals which have access to it, to escalate their rights in a cluster to cluster-admin , as they can create new clusterrolebindings. There's a worked example of gaining cluster-admin rights via the bind verb here
