When releasing the versioned assets work, we stumbled on a problem with old pickled
versions of the StaticContent objects residing in cache, which triggered a bug in the
code. Not wanting to blow away all cached items, we ended up having to revert and add
in some backwards-compatible helper code to ease the transition.
With this, we'll now utilize the version argument that Django's caching interface
allows, in conjunction with a constant value that can be modified when breaking changes
are being made, to let us gracefully ignore older cached course assets.
We're seeing errors in NR from objects read out of the cache lacking the
'StaticContent' object has no attribute 'content_digest'

This reverts commit 849ebc5f22.
This commit "undoes"a previous hotfix, and allows a cms course_publish
signal to trigger a block_structure update_course_in_cache task, which
is run on an lms worker queue.
Changes:
-exposes ALTERNATE_QUEUE_ENVS
-adds routing layer in celery.py
-moves prior dev_with_worker settings file to devstack_with_worker
-moves course_block api functionality into openedx/core/djangoapps/content/block_structure
This moves the functionality of the 'export_course' management command from lms/djangoapps/courseware
over to the Studio codebase. This reflects its use going forward to be run with cms settings, to
export the content of the Studio modulestore instead of the LMS modulestore. The management
command is used by an analytics workflow to output course content for researchers.
By default, disable all caching in tests, to preserve test independence.
In order to enable caching, inherit from CacheSetupMixin, and specify
which cache configuration is needed.

[PERF-303] Integer XBlocks/XModules into the static asset pipeline.
This PR, based on hackathon work from Christina/Andy, implements a way to discover all installed XBlocks and XModules and to enumerate their public assets, then pulling them in during the collectstatic phase and hashing them. In turn, the methods for generating URLs to resources will then returned the hashed name for assets, allowing them to be served from nginx/CDNs, and cached heavily.
