Add metric counters to capture the RocksDB checkpointing statistics.

> As per the discussion with [~anu] on HDDS-1085, this JIRA tracks the effort
> to add metric counters to capture ROcksDB checkpointing performance.
> From [~anu]'s comments, it might be interesting to have 3 counters – or a map
> of counters.
> * How much time are we taking for each CheckPoint
> * How much time are we taking for each Tar operation – along with sizes
> * How much time are we taking for the transfer.
