Subject: [PATCH] Lower Docker req to 19, make sure we test locally

Ref #15

``` $ docker --version
Docker version 19.03.11, build 42e35e6
```

But abra works. So I think 19 might be sufficient?

Also, wondering if we should add `DOCKER_CONTEXT=default` to that check,
to make sure we're not querying a remote server. (Semi-related question
- should we also check remote Docker versions?)
