Remove SSH support from nodepool
As we move forward with zuulv3, we no longer need to ability to SSH into a node from nodepool-launcher. This means we can remove SSH private keys from production server. Now we only keyscan the node and pass the info to zuul to do SSH operations. We also create out own socket now for paramiko, so we can better control the exception handling.
