We have previously tried building a full cloudprovider in e2e for AWS; this wasn't the best idea, because e2e runs on a different machine than normal operations, and often doesn't even run in AWS. In turn, this meant that the cloudprovider had to do extra work and have extra code, which we would like to get rid of. Indeed, I got rid of some code which tolerated not running in AWS, and this broke e2e.
