Add support for using Qpid instead of RabbitMQ.

To use Qpid instead of RabbitMQ, you set 'qpid' instead of 'rabbit' in
ENABLED_SERVICES in your localrc file. Otherwise, RabbitMQ is still
used by default.

(dtroyer) fixed problem with service test that failed to configure
rabbitmq if it was still selected.
