This allows us to deploy much faster: all we have to do is to copy the
assets from the container to the shared volume.
We also changed the way themes are managed: similarly to static assets,
they are now packaged inside the docker image.
By default, open response assessment files are sent to S3. Here, we
store uploaded files with the "filesystem" backend instead. To do so, we
must install a forked version of ora2 that fixes a couple issues.
Note that the "django" backend is not very usable, as file extensions
are lost on upload.

webpack requires the NODE_ENV environment variable which is incorrectly
set "paver update_assets" in development mode. To avoid this issue, we
split update_assets into its subparts.
The `update_assets` paver task of the lms/cms attempt to manually
uninstall some old packages. We should not concern ourselves by this,
since all requirements are installed from scratch in every docker image.
Close #73.
We replace the custom script wait-for-greenlight by dockerize: it is a
generic tool that allows for different services to be up. Also, on day,
it will allow us to generate config files dynamically (maybe).
Xqueue containers consist of two services: a gunicorn service, that
receives requests from LMS/CMS, and a worker service. I guess the worker
service receives orders from the gunicorn service, through rabbitmq.
(but I'm less than certain about that).
While adding xqueue containers, we refactored the way mysql databases
are created, and how the root password is loaded. Also, we silenced some
options from the configure script.
Images are no longer built locally, Instead, they are downloaded from
docker hub. This completely changes config file organisation. In
particular, we no longer copy configuration files to the original docker
image.
XModule could not be found because the compiled package could not be
found in edx-platform/common/lib/xmodule. This was due to the fact that
build operations realised after a VOLUME statement are ignored if they
affect the content of this volume (although it's not mounted during
build, of course). This is not a bug, it's a feature of the VOLUME
statement :)
