### Search before asking - [x] I searched in the [issues](https://github.com/apache/fluss/issues) and found nothing similar. ### Description Fluss supports graceful shutdown, however the properties used are hardcoded into the TabletServer ``` private static final int CONTROLLED_SHUTDOWN_MAX_RETRIES = 3; private static final long CONTROLLED_SHUTDOWN_RETRY_INTERVAL_MS = 1000L; ``` see [here](https://github.com/apache/fluss/blob/main/fluss-server/src/main/java/org/apache/fluss/server/tablet/TabletServer.java#L89) We can make these configurable. ### Willingness to contribute - [ ] I'm willing to submit a PR!
