This introduces a mechanism to control the time-to-live for an unlocked
course asset, which will allow browsers and intermediate proxies/caches
to cache these course assets, determinstically.
Locked assets, with their nature of requiring authorization, are not
eligible for caching.
Comprehensive theming did not work with django templates (used by course wiki).
The reason it didn't work was that in order for the theme to work, theme template folder
has to be added to django template dirs setting *before* django startup.
After django startup, modifying `settings.DEFAULT_TEMPLATE_ENGINE['DIRS']` has no effect,
because at that point the template engine is already initialized with a copy of the
template dirs list.
Instead of running the theme startup code as an autostartup hook, we manually run it
*before* `django.setup()`. This is fine because theme startup code doesn't have to do
anything else besides modifying some settings and doesn't actually need django to be
initialized.
Adding the declaration of the settings object to openedx.conf to be able to import it from a nicer location
Resolving quality violations
Merging dicts with the settings definition when they exist in the microsite configuration
Using a cache to improve the perfomance of quering any dictionary in the microsite definition
Ignoring the invalid-name pylint warning since the names must be kept thsi way to stay the same as the ones in django.
Removing the default dict argument as per https://docs.python.org/2/tutorial/controlflow.html#default-argument-values
Extracting the implementation of the microsite to a selectable backend.
Leaving the function startup.enable_microsites for backwards compatibilityy
Adding a database backend
Using a cache to improve the perfomance of quering any dictionary in the microsite definition.
Changed the database backend so that it extends the settings file backend and removed all the unnecessary methods.
Using the backend provider for the get_dict function
some tweeks and some initial unit tests
Using getattr as a function insteal of calling the underlying __getattr__ directly
Adding an ModelAdmin object for the microsite model in the django-admin panel

consolidate/refactor some shared code
add config to aws.py and add migration files
fix tests
Changes to get the backends to run after the refactor
add archiving capabilities to microsites. Also make a few notes about performance improvements to make
