Chef::Knife::Bootstrap::ClientBuilder#sanity_check

Check for the existence of a node and/or client already on the server.  If the node
already exists, we must delete it in order to proceed so that we can create a new node
object with the permissions of the new client.  There is a use case for creating a new
client and wiring it up to a precreated node object, but we do currently support that.

We prompt the user about what to do and will fail hard if we do not get confirmation to
delete any prior node/client objects.
