Service Upgrade: With default readiness check, the status of upgrade is reported to be successful prematurely

With YARN-9071 we do clear the IP address and Hostname from AM, NM and yarn registry before upgrade. However it is observed that after the container is launched again as part of reinit, the ContainerStatus received from NM has an IP and host even though the container fails as soon as it is launched.

On Yarn Service side this results in the component instance transitioning to READY state when it checks just the presence of IP address.
