      Description

      This JIRA proposes to measure the time the of lock of FsDatasetImpl is held by a thread. Doing so will allow us to measure lock statistics.

      This can be done by extending the AutoCloseableLock lock object in FsDatasetImpl. In the future we can also consider replacing the lock with a read-write lock.
