Add a downgrade command, so you can reverse the upgrade process and go back to Kamal 1.9. This replaces kamal-proxy and reboots all the accessories. This gives an upgrade and downgrade path: Upgrade: 1. Upgrade config to be Kamal 2 compatible + use kamal 2.0 2. Run `kamal upgrade` Downgrade: 1. Switch back to previous config + use kamal 1.9 2. Run `kamal downgrade` You can set `--rolling` to downgrade one host at a time.
