Add config for ssh-key import and consuming user-data
This patch enables control over SSH public-key import and
discarding supplied user-data (both disabled by default).
allow-userdata: false
ssh:
allow_public_ssh_keys: false
This feature enables closed appliances to prevent customers
from unintentionally breaking the appliance which were
not designed for user interaction.
The downstream change for this is here:
