This has triggered an OOM in a process which was churning through s3a fs instances; the increased memory footprint of IOStatistics amplified what must have been a long standing issue. * Makes sure instrumentation is closed when fs is closed * Uses a weak reference from metrics to instrumentation, so even if the fs wasn't closed (see HADOOP-18478), this ref would not be holding things back. ### How was this patch tested? cloud tests. no new tests...if there are suggestions, that'd be good ### For code changes: - [X] Does the title or this PR starts with the corresponding JIRA issue id (e.g. 'HADOOP-17799.
