    tier/libgfdb: Ordering query results from libgfdb

    When querying we will order the query result to get
    the hotest or the coldest files in the queried list
    so that these files are migrated first.

    Now here we are giving priority to the write heat(time and counters),
    as it requires complex queries to have a composite
    ordering of write and read + it has it impact on performance.
