This bug is to track the work of getting a message between RelEng automation and the upcoming QA automation for the rapid betas - this can be email at first, but later maybe using a message queue (releng already uses rabbitmq). There will need to be a message accepted that will be sent from RelEng automation to QA automation to trigger the testing, then when testing completes successfully there will need to be a message sent back to RelEng.

We already listen for build messages and start testing the builds. The only necessary token we need here is the feedback once tests have been finished. We could make use of the QA consumer?
