boolean handleRemoteCreateBackupRegion(int bucketId) {
    return false;
  }
Checks if this PR has the capacity to handle the rebalancing size. If so, creates the real
storage for the bucket and a bucket2Node Region mapping. These two operations are done as a
logical unit so that the node can immediately begin handling remote requests once the
bucket2Node mapping becomes visible.
