AutoQA Upgrade to 0.7

[Tim Flink]

As a heads up, we're updating AutoQA to 0.7 today. I'm not expecting
any issues during the update process but no new jobs will be run while
we're updating the production systems. The update process shouldn't
take much more than an hour, maybe two if we hit problems.

If all goes well, you might notice a delay in results being posted to
bodhi. If all doesn't go well, you'll see another email from me.
