What is the purpose of the change

Removed setting rest.address to the actual IP address of the Yarn NodeManager in order to support dual network environment.

Given the Hadoop Yarn cluster with dual networks:

• 192.168.x.x: For data transfer. Speed: 10Gbps.
• 10.x.x.x: For management only. Speed: 1Gbps.

A client outside the Hadoop Yarn cluster is configured, with management network only(10.x.x.x) and data transfer high speed network not accessible. To reproduce, we sumbit a Flink job from this client(Batch word count for example), the job can be successfully submitted but the result cannot be retrieved, with the exception: Connection refused: {jobmanager_hostname}:{jm_port}. The root cause is the job manager rest address is bind to its actual address (192.168.x.x) rather than 0.0.0.0. Manually setting rest.bind-address does not work.

One of the changes in Flink-24474 in YarnEntrypointUtils overwrites RestOptions.BIND_ADDRESS to the node's actual address. This change should be reverted.

@paul8263 Logic LGTM, but pls. add a unit test to YarnEntrypointUtilsTest that validates we keep the preconfigured value.
