[BLOCKED] Appliance console copy keys

This copies fetches keys from a remote machine.

Tested workflows in appliance_console (choosing all the prompts)
Tested in cli

Current issue - only works with gem `net-ssh` versions 2.8.0 and 2.9.1
Note: `net-scp` is pretty old, but it works great.
I did notice we pegged `net-ssh` to 2.6.5 for an old version of fog that we are no longer using.
We would need to test our exposure to this gem.
Why is the say before the expectations in these examples?
