Story points:


arvados-docker-cleaner currently instantiates docker.Client() without any arguments. In this case, the docker module has a hardcoded constant API version that it tries to use. If that version is newer than the server supports, the connection will fail.

Determine the lowest API version that arvados-docker-cleaner can use, and pass that string as a version kwarg to docker.Client(). If that's too difficult to do, or causes other problems, consider also specifying version='auto'—this will use the server's native API version.

Declaring the version we know we want is ideal. See what the oldest version(s) supported by current Docker are. If they're old enough to be supported by much-older Docker (like, around 1.3), declare that. Otherwise, declare 'auto'.

This is caused by a race condition in a Python SDK tool that sometimes causes it to write some extra errors as it exits. It's not related to this change: Docker cleaner doesn't use the SDK at all, and vice versa. I'm going to push accordingly. Thanks.
