Add support for using Qpid instead of RabbitMQ.

russellb · Dean Troyer · commit 4a221459b728 · 2012-05-17T14:35:44.000-05:00
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.
