    Enables db2 server disconnects to be handled pessimistically

    A checkout listener can be added to sqlalchemy to be able to
    handle database disconnect pessimistically and avoid an error in
    the event of a DB restart or simply a temp connection issue due
    to network glitches. At the moment only mysql is enabled with
    this feature. This patch enables db2 as well.
