> Add metrics to the datanode to count the number of volumes and volumes in each health state:
> * `TotalVolumes`: The total number of volumes on the datanode regardless of health state.
> ** Useful to identify mount issues where the number of volumes the datanode sees is less than expected.
> * `NumHealthyVolumes`: The total number of healthy volumes on the datanode.
> * `NumFailedVolumes`: The total number of failed volumes on the datanode.
> These counts can be aggregated for both data and metadata volumes.
