Description

Currently, Flink Client can only connect to the server through the address:port, which is configured by the rest.address and rest.port.

But when running Flink on Kubernetes and exposing services through ingress. The URL to access the Flink server should be: http://\{proxy address}/{some prefix path to identify flink clusters}/{flink real path}

I'd like to introduce an option named "rest.url-prefix" to support adding a prefix to URLs in RestClient.
