- Replaced calls to docker-sync-daemon with docker-sync, which is now daemon by default
- Moved from rsync strategy to native_osx, which is the new default
- Using :nocopy to avoid issues when syncing to named volumes

Fixes #110

This will enable others to build images.

This environment variable instructs edxapp to NOT remove old Python libs when install prerequisites since our images/containers will never have the older versions.

Despite the environment variable overrides, Paver still seems to be  doing more than is necessary to start LMS and Studio. Skip Paver, and run the server directly via Django's manage.py, like every other service.

Additionally, the removal of old Python libraries has been disabled when installing prerequisites. This is not necessary for Docker images, and removing packages causes Django to stop and the container to shut down.

* Start docker-sync and use the local host volumes by default
* Make the devstack workspace configurable, make travis use /tmp
* Remove redundant env vars, set -d on make devstack.up
* Add sleep to travis.yml
* Set a default value for DEVSTACK_WORKSPACE, and export it to all subshells in Make
* Rename devstack prefix to dev, add comment to makefile target
* Edits to the README to encourage setting up docker-sync before getting
started. Also update references to make targets.

The configuration changes for these images has been merged to the master
branch of edx/configuration. We can now pull from the "official" latest
tag rather than devstack.

Also make destroy.sh delete anonymous disks (use -v with docker-compose)

* Due to behavior of manage.py runserver, move docker-compose up to after
loading the database
* Run make provision as part of travis build
* Use --initial-only flag with countries provisioning for ecomm
* Serialize provision.sh and set -x for tracing
* Restart LMS container after running install prereqs due to error resulting
in LMS crashing
* Skip discovery tasks until fix is made to index validation
* Remove 'make validation' from .travis.yml, since it doesn't work
  'make provision' tells us everything we need to know

The dependency on the discovery service by credentials and ecommerce is not necessary. Having this dependency unnecessarily brings up the discovery and elasticsearch services when we want to run a single service.

Resolves #83.

This service has been split into two to ease management in devstack.
Provisioning commands will now operate on the LMS container.

Our initial desire to make development look like production by using nginx and supervisor is conflicting with our goal of easing local development pains. Specifically, front-end development requires re-compiling/collecting static assets with every change. Using Django to serve the applications alleviates this pain and allows developers to maintain their current workflows.

by devstack.provision

The merging of these two steps causes confusion when the prereq installation fails, preventing migrations from being run, yet the provisioning process continues. Splitting them out will ensure that users are aware when provisioning fails.

See #72

Static assets are installed/compiled when the images are built. Sharing
these files from the host usually results in assets needing to be
recompiled unnecessarily. Excluding them eliminates confusion around
this process and ensures only the source code is shared.

Provisioning the service will now refresh the metdata from the dependent services and update the search index.
