Have update_users only happen when services are running

Right now, it would run unless you are skip-tags'ing it (which is sort
of what we do in docker builds) or if the image has access to a database
(which is what happens during production builds).  It should instead be
explicitly requested.  I would remove it entirely, but we really want it
to run during sandbox builds, which use the ansible role.

Add devpi and devpi_consumer roles and devpi Docker container.

We chose not to be running supervisor, remove it from the command

Remove xqueue SERVICE_VARIANT and old variables

Bump awscli from 1.14.44 to 1.14.45

Bumps [awscli](http://aws.amazon.com/cli/) from 1.14.44 to 1.14.45.

Give xqueue a devstack.sh

It was never used the way it is in edxapp.

Also remove old pre-ginkgo variables S3_BUCKET and S3_PATH_PREFIX

If we move away from runserver, we can switch back.  Possible someone
will want to push commands into this, and away from the docker compose
file, but that's not the current state.

Also clean up some really old unused files I spotted while grepping
through the builds.

This shell wrapper brings it in line with the rest of the `make
foo-shell` commands and puts you in a better location in the container.
It also makes running tests easier since it sets up the virtualenv and
puts you in the right place to type `make test`
