		Move a local device to a fleet on another balena server.

		Move a local device to a fleet on another balena server, causing
		the device to "join" the new server. The device must be running balenaOS.

		For example, you could provision a device against an openBalena installation
		where you perform end-to-end tests and then move it to balenaCloud when it's
		ready for production.

		To move a device between fleets on the same server, use the
		\`balena device move\` command instead of \`balena join\`.

		If you don't specify a device hostname or IP, this command will automatically
		scan the local network for balenaOS devices and prompt you to select one
		from an interactive picker. This may require administrator/root privileges.
		Likewise, if the fleet option is not provided then a picker will be shown.

		${applicationIdInfo.split('\n').join('\n\t\t')}
