When we use the following command to start a Flink application cluster, the specified hostname could not take effect. The root cause is HOST_OPTION is not added to options in StandaloneApplicationClusterConfigurationParserFactory. It will be a critical issue when we deploy Flink on container environment. Because users usually want to specify a given hostname.
For the old StandaloneJobClusterConfigurationParserFactory, it has the same issue.
