Inject a configuration file into a device or OS image.
Inject a config.json file to a mounted filesystem, e.g. the SD card of a
provisioned device or balenaOS image.
Note: if using a private/custom device type, please ensure you are logged in
('balena login' command). Public device types do not require logging in.
