Got 503 when get queue with sqlalchemy

[Feilong Wang]

When using sql as the management plane and get queue, user will run into 503 error since we're using self.driver.get, but unfortunately, there is no get() method in sqlalchemy's ControlDriver.

    Fix GET queue metadata for sqlalchemy

    When using sql as the management plane and get queue, user
    will run into 503 error since we're using self.driver.get,
    but unfortunately, there is no get() method in sqlalchemy's
    ControlDriver. This patch fixes the issue by using run()
    instead of get().
