expose vm via ssh

[karmab]

a couple of virtctl expose examples should do the trick actually
something like virtctl expose virtualmachineinstance vm1--name vmiservice --port 27017 --target-port 22 and making sure the port 27017 is publicly accessible

[karmab]

added port 27017 to the existing firewall rule on our cnvlab gcp project (matches all instances created with the cnvlab tag)
