### Description of PR The JournalNodeSyncer will include the local instance in syncing when using a bind host (e.g. 0.0.0.0). There is a mechanism that is supposed to exclude the local instance, but it doesn't recognize the meta-address as a local address. Running with bind addresses set to 0.0.0.0, the JournalNodeSyncer will log attempts to sync with itself as part of the normal syncing rotation. For an HA configuration running 3 JournalNodes, the "other" list used by the JournalNodeSyncer will include 3 proxies. Exclude bound local addresses, including the use of a wildcard address in the bound host configurations. ### How was this patch tested? An additional unit tests was added to verify the call getJournalAddrList dropped the current instance. Integration tests were conducted in HA configuration in Kubernetes, running Java 11. After the patch, all JournalNodes stopped attempting to sync with themselves. ### For code changes: - [X] Does the title or this PR starts with the corresponding JIRA issue id (e.g. 'HADOOP-17799.
