HDFS-11534 introduced some useful metrics for blocks count in pending IBR.
{noformat}
  @Metric("Count of blocks in pending IBR")
  private MutableGaugeLong blocksInPendingIBR;
  @Metric("Count of blocks at receiving status in pending IBR")
  private MutableGaugeLong blocksReceivingInPendingIBR;
  @Metric("Count of blocks at received status in pending IBR")
  private MutableGaugeLong blocksReceivedInPendingIBR;
{noformat}
It will be nice to have in the metrics documentation.
