Refactored parallel execute and execute create into a single function
parallel_execute that can now handle both cases. This helps untangle it
from being so tightly coupled to the container.
Updated all the relevant operations to use the refactored function.

The concurrent.futures backport doesn't play well with
KeyboardInterrupt, so I'm using Thread and Queue instead.
Since thread pooling would likely be a pain to implement, I've just
removed `COMPOSE_MAX_WORKERS` for now. We'll implement it later if we
decide we need it.

Sometimes, some messages were being executed at the same time, meaning
that the status wasn't being overwritten, it was displaying on a
separate line for both doing and done messages.
Rather than trying to have both sets of statuses being written out
concurrently, we write out all of the doing messages first. Then
the done messages are written out/updated, as they are completed.

There's significant speed improvement by having more workers. This
value still shouldn't cause anyone's machines to melt/explode.

This approach takes the style of replacing the output message, in
place, when the command has finished executing. Bringing it a bit
more inline with what `docker pull` does.

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

Rather than creating a docker client within each test, create one
at setup and make it accessible to the whole class.
