> Add fine-grained locks metrics in DataSetLockManager

> Currently we use fine-grained locks to manage FsDataSetImpl. But we did not
> add lock-related metrics. In some cases, we actually need lock-holding
> information to understand the time-consuming lock-holding of a certain
> operation. Using this information, we can also optimize some long-term lock
> operations as early as possible.
