What changes were proposed in this pull request?
When a datanode re-registers with SCM or sends heartbeats after gaining new ports (e.g. RATIS_DATASTREAM when dfs.container.ratis.datastream.enabled is enabled), SCM does not update the stored DatanodeDetails in the node registry unless IP, hostname, or software version also changed. Port-only updates are ignored.
This JIRA propose to re-registration path (SCMNodeManager.register()) to update the port if there is any change detected.
