This is especially useful on Kubernetes. With this change, the forum
container no longer crashes whenever mongodb or elasticsearch are
unavailable. Instead, it just waits for thoses services to be up.
Previously, we could not run forum migrations in Kubernetes because they
relied on exec-ing the migration command in the running container -- and
there was no such container, because the services where not already up.
Configuration loading was overly complex. Here, we simplify it
drastically with reasonable defaults. Hacky additional variables are
unncessary now that we use custom jinja2 filters.
For initializing the mysql database, we now run the mysql client from
the mysql container. That means that the mysql client is no longer
required in the openedx container, as previously suggested in PR #209.
When running `pip install -r /path/to/x.txt`, relative paths listed in
x.txt are supposed to be relative to the current folder, and not the
x.txt folder. This results in an error during `pip install`:
./xblock-poll/ should either be a path to a local project or a VCS
url beginning with svn+, git+, hg+, or bzr+
This error was first reported here:

Tutor is not using any bash-specific feature.
This commit changes (almost) all invocations to /bin/bash replacing them with
/bin/sh. It allows building a docker image that does not bundle bash in it.
The file k8s.py still has a bash invocation, to make sure this change does not
impact functionality for any user.
Given that each gunicorn worker uses ~200-250Mb virtual memory, we should
really avoid running too many of them. Here, we reduce the default
number of workers to 2. For the LMS and the CMS, this number can be
adjusted by setting an environment variable GUNICORN_WORKERS.
This is related to #207.
Settings the number of workers for the LMS and the CMS to 2*|CPU|+1
results in 4*|CPU]+2 gunicorn workers, which is too much for a laptop to
cope with.
Close #207
Migrations were being done on openedx-assets, which does not depend on
mysql. As a consequence, the mysql container was not being created on
"migrate" and migrations were failing with "Timeout after 20s".
