Resolve SSH proxy routing hang in prod by fixing dual IP assignment on same network.

Closes #181 (closed)

Defining a network can be optional when a port is already defined when deploying a VM.

This commit adds flexibility where you can either use --port or --network options to define a network during the deployment.

Alternatively, you can define both but the port cannot be from the same network you used in the --network option. Otherwise, you will have two ips from the same network which will cause network reachability issues.
