Commands able to use this parallelisation are `stop`, `kill` and `rm`.
We're using a backported function from python 3, to allow us to make
the most of a pool of threads without having to write the low level
code for managing this ourselves.
A default value for number of threads is a low enough number so it
shouldn't cause performance problems but if someone knows the
capability of their system and wants to increase it, they can via
an environment variable DEFAULT_MAX_WORKERS

Also warn the user about the one-off containers in the standard error
message about legacy containers.

If you have an alternate YAML file with different services defined,
containers for those services will be shown in `docker-compose ps` even
if you don't pass that file in.
Furthermore, `docker-compose rm` will claim that it's going to remove
them, but actually won't.

When an upstream dependency (e.g. a db) has a container but a downstream
service (e.g. a web app) doesn't, a web container is not created on
`docker-compose up`.

- Rename `migration` module to `legacy` to make its legacy-ness explicit
- Move `check_for_legacy_containers` into `legacy` module
- Fix migration test so it can be run in isolation

If we're just streaming logs from `docker-compose up`, we don't need
to set AttachStdin/out/err, and doing so results in containers with
different configuration depending on whether `up` or `run` were invoked
with `-d` or not.
