    Don't raise MySQL 2013 'Lost connection' errors

    Although this code error is part of the `ping_listener` tests, it
    missing from the list of known - and ignored - connection errors.

    The code error 2013 refers to a connection lost during a query, see:
    https://dev.mysql.com/doc/refman/5.0/en/error-messages-client.html#error_cr_server_lost

    Without this error code, the session won't try to reconnect to mysql,
    which makes `max_retries` useless.
