What happened

Env: Datasophon v1.2.0

Try to pass ${host} from startRunner's args of service_ddl.json to "start-stop" shell script but not affeccted, just get a literal text "${host}" in the shell script.

What you expected to happen

Placeholder variable(s) of service_ddl.json passed to backend "start-stop" shell script can be recognized and replaced correctly.

How to reproduce

1. Write startRunner args with placeholder variable ${host}.
2. Get ${host} variable in "start-stop" script control-flink.sh.
3. Start the role on datasophon-webui, then see the log.

Sorry, your questions are pointless, actually this issue is just saying currently datasophon (in shell script) cannot support recognize and replace placeholder variable(s) (like '${xxx}') correctly which passed through service_ddl.json's startRunner args.
