+        final Map<String, String> clusterUUIDGraph = manifestsByClusterUUID.values()
+            .stream()
+            .collect(Collectors.toMap(ClusterMetadataManifest::getClusterUUID, ClusterMetadataManifest::getPreviousClusterUUID));


can there be cases of isolated masters where more than 1 master can be publishing the metadata? how are we handling such cases?

multiple cluster managers can only exist intermittently and one of the cluster managers will fail when they try to validate the quorum since another cluster manager is holding the quorum now. during publish and commit phase, quorum of cluster manager nodes need to approve of the operation.

such cases are handed by ensuring we always pick a committed uuid from remote(isInvalidClusterUUID) and trim any duplicate UUIDs using our trimming logic
