Appliance console copy keys

This copies fetches keys from a remote machine.

Tested workflows in appliance_console (choosing all the prompts)
Tested in cli

blocked on #550
Sometimes running the specs were failing here depending upon if it had encountered a require `active_support/all`

In runtime, it requires vmdb/Gemfile, so we know active_support is included.
But when running rspec (and using lib/Gemfile) is was failing at odd times.

I will revisit/investigate
