Kevin Falcone 6f9a3911e5 Implement a BaseStudentModuleHistory 
This abstract class contains most of the fields (aside from the id and
foreign key to StudentModule that the subclasses need to manage).  It
also provides a get_history method that abstracts searching across
multiple backends.

Move router code to openedx/core
We need to use it from cms and lms.
Ensure aws_migrate can be used for migrating both the lms and cms.

Handle queries directed to student_module_history vs default and the
extra queries generated by Django 1.8 (SAVEPOINTS, etc).

Additionally, flag testing classes as multi_db so that Django will
flush the non-default database between unit tests.

Further decouple the foreignkey relation between csm and csmhe

When calling StudentModule().delete() Django will try to delete CSMHE
objects, but naively does so in the database, not by consulting the
database router.

Instead, we disable django cascading deletes and listen for post_delete
signals and clean up CSMHE by hand.

Add feature flags for CSMHE
One to turn it on/off so we can control the deploy.
The other will control whether or not we read from two database tables
or one when searching.

Update tests to explicitly use this get_history method rather than
looking directly into StudentModuleHistory or
StudentModuleHistoryExtended.

Inform lettuce to avoid the coursewarehistoryextended app

Otherwise it fails when it can't find features/ in that app.

Add Pg support, this is not tested automatically.

"""
This is the common settings file, intended to set sane defaults. If you have a
piece of configuration that's dependent on a set of feature flags being set,
then create a function that returns the calculated value based on the value of
FEATURES[...]. Modules that extend this one can change the feature
configuration in an environment specific config file and re-calculate those
values.
We should make a method that calls all these config methods so that you just
make one call at the end of your site-specific dev file to reset all the
dependent variables (like INSTALLED_APPS) for you.
Longer TODO:
1. Right now our treatment of static content in general and in particular
course-specific static content is haphazard.
2. We should have a more disciplined approach to feature flagging, even if it
just means that we stick them in a dict called FEATURES.
3. We need to handle configuration for multiple courses. This could be as
multiple sites, but we do need a way to map their data assets.
When refering to XBlocks, we use the entry-point name. For example,
| setup(
| name='xblock-foobar',
| version='0.1',
| packages=[
| 'foobar_xblock',
| ],
| entry_points={
| 'xblock.v1': [
| 'foobar-block = foobar_xblock:FoobarBlock',
| # ^^^^^^^^^^^^ This is the one you want.
| ]
| },

# 2. List all instances of that XBlock on the top of the course outline page asking
# course authors to delete or replace the instances.
