manager's stdout if it does not exist
                 Key: FLINK-31233

When running Flink on Kubernetes, the stdout logs is not redirected to files so 
it will not shown in WEB UI as expected.

But It returns “500 Internal error” in REST API and produces an error log in 
jobmanager.log. This is confusing and misleading.

 

I think this API should return “404 Not Found” without any error logs, similar 
to how jobmanager/stdout works.
