Adds support for maintenance mode to Kamal. There are two new commands: - `kamal app maintenance` - puts the app in maintenance mode - `kamal app live` - puts the app back in live mode In maintenance mode, the kamal proxy will respond to requests with a 503 status code. It will use an error page built into kamal proxy. You can use your own error page by setting `error_pages_path` in the configuration. This will copy any 4xx.html or 5xx.html files from that page to a volume mounted into the proxy container.
