Hi, Currently `sql-gateway` can be started with the script `sql-gateway.sh` in an existing node, it is more like a simple "standalone" node. I think it's valuable if we can do more work to start it in k8s.
For xiaolong: Do you want to start a sql-gateway instance in the jobmanager pod? I think maybe we need a script like `kubernetes-sql-gatewah.sh` to start `sql-gateway` pods with a flink image, what do you think?
