Other doorbot hostnames and ssh credentials should be installed

It's useful to be able to ssh from one doorbot to another with just "ssh doorbot2" for example.

The /etc/hosts should have the doorbots added to it during the setup process (or we should move to using doorbotX.local and mDNS).

Plus we should copy across SSH keys for the new doorbot so we don't have to enter the password each time.
