This introduces:
* A new XBlock runtime that can read and write XBlocks that are persisted using
Blockstore instead of Modulestore. The new runtime is currently isolated so
that it can be tested without risk to the current courseware/runtime.
* Content Libraries v2, which store XBlocks in Blockstore not modulestore
* An API Client for Blockstore
* "Learning Context" plugin API. A learning context is a more abstract concept
than a course; it's a collection of XBlocks that serves some learning purpose.
This reverts commit 3d2617983b.
The change was not quite right because the method six provides needs to
have `self` be passed in as well. See the docs here:
https://six.readthedocs.io/#unittest-assertions
Reverting for now and we can fix it in smaller chunks later.
* Remove old performance tests that we haven't been running.
As far as I can tell, these tests to capture HAR files were created 5
years ago and not being run as a part of our suite? They capture HAR
data that we do nothing with so even if they were running we should
remove them until we're ready to care about consuming this kind of
information.
* Update password test unicode string.
* Add ugettext translation helper function.
* Fix lambda syntax that is not valid in python 3.
* Fix ur raw strings which his not valid in python 3
* Use edx_six.get_gettext instead of ugettext.
* Fix a few other encoding issues.
* Don't use old form of sorted funciton.
This form which uses a 'cmp' method is not available in python 3.
* Convert to using ExitStack instead of nested.
nested is not available in Python3.
* Use ExitStack from contextlib2.
ExitStack has not been backported to the Python 2.7 standard library and
contextlib.nested is no longer available in Python 3.5. We need to be
able to use something in both 2 and 3 as we transition so we'll pull in
contextlib2 which has backports of the full python3 contextlib.
