Service group's DB driver dies if local conductor is used

[Brian Elliott]

If using local conductor, the DB driver for servicegroup is subject to failure. It is currently only catching MessagingTimeout exceptions, which will not occur as there is no indirection API present.

In the event of a temporary DB connection issue, the DB driver will not recover if local conductor is used.

    Handle DB failures in servicegroup DB driver

    Fix an issue where when local conductor is used, the DB driver for
    servicegroup will not handle transient DB problems gracefully. The
    patch makes the behavior consistent with messaging timeouts if remote
    conductor is used.
