Deployment tests

There are a lot of chunks of code like this where you're doing the same thing to all four nodes. Why not:

    for node in ['195', '196', '197', '198']:
        api.project_connect_node('anvil-nextgen', node)

As a bonus, this makes it easier to generalize, which we're goint to have to do soon, so we can run this on our newer dev seup.
