    Dispose db connections pool on disconnect

    When a disconnect happens (e.g. when VIP moves to another node), all
    existing connections in the pool become invalid. There is no sense to
    check every single connection in the pool, as this may take a long
    time (e.g. when python-mysqldb driver is used with eventlet green
    threads, there is no context switch on db IO, so the whole process is
    blocked until socket read times out). Dispose all connections in the
    pool when disconnect is detected, they will be recreated on demand
    then.
