Relates to #486 . In order for us to lower the bus factor, we need to be able to have access to the production instances so that we can do deploys in case of need.

If we end up using something like Ansible, or similar, that means that we can still run the deployment commands from our local computer and Ansible will essentially log via SSH under the hood, which means that the CLI command will be available for all the people downloading this project (because that's open source, of course) but only trusted developers will be able to actually deploy (or release, for what is worth, we need a similar strategy there as well).

@fmaniere Do you think you can add my and @cgenie 's SSH public keys to the relevant hosts? We can start with dev.sub for now which is relatively low-impact as far as I can tell.
