`balena join` does not run on production balenaOS images

[pdcastro]

It has been reported (e.g. here and here) that the balena join command only works successfully on development balenaOS images (see dev vs prod images).

It has been suggested that the reason (bug) is that balena join uses ssh under the hood, but production images require a manual ssh key setup for ssh to work with the root user account (sshKeys setting in config.json).

Known workarounds:

• Add a ssh key to config.json.
• Alternatively, use balena ssh to open a ssh terminal to the device's host OS, then directly execute the os-config leave/join command.
