DRILL-5863: Sortable table incorrectly sorts fragments/time lexically
The DataTables jQuery library sorts data based on the value of the element in a column.
However, since Drill publishes sortable items like fragment IDs and time durations as non-numeric text, the sorting is incorrect.
This PR fixes the fragment and duration ordering based on their implicit numeric values (minor ID and millisecond representation, respectively).
Support memory chaining
