* Moving plugins infrastructure to edx-django-utils
This PR extracts the code that enables plugins in edx-platform and puts it in edx-django-utils. This is done to allow other IDAS to add plugin functionality.
The Randomized Content Block XBlock only randomizes the selection of
the children blocks and has unpredictable randomization of
the order of the selected child blocks due to the usage of sets, which
are unordered, for storing the selected blocks. This becomes apparent
when all the available child blocks in a library are chosen for a
Randomized Content Block, to randomize just the order of the child
blocks and not just the selection of the blocks. The order of the
selected blocks ends up being similar for multiple learners.
This change modifies the XBlock to store the selected child blocks in
a list, instead of a set, after randomly shuffling them.
A new block structure transformer, ContentLibraryOrderTransformer has
been added to transform the order of the selected children XBlocks to
match the order of the selections made in the
ContentLibraryTransformer. This ensures that same correct randomized order
of blocks is also returned by the course blocks API.
This effectively evaluates the flag outside of the context of a course.
This was previously available through `.is_enabled_without_course_context`,
which has been removed in favor of simply `is_enabled()`.
This was done to make the CourseWaffleFlag interface more uniform with
that of WaffleFlag and ExperimentWaffleFlag and eliminate unecessary
branching when handling CourseWaffleFlags.
For the Courseware MFE rollout experiment, we want users'
default buckets to be consistent across course runs.
ExperimentWaffleFlag advised that this could be done
by calling `.is_enabled(...)` without a course_key argument;
however, doing so breaks when uing the main_flag.BUCKET_NUM
scheme to apply bucket rules for a specific set of users
or courses.
This commit explicitly adds course-unaware-bucketing via
a new kwarg to ExperimentWaffleFlag.__init__ method.
Furthermore, it fixes ExperimentWaffleFlag.is_enabled(course_key=None)
to work as advertised, by means of calling
.is_enabled_without_course_context on its subordinate flags.

- Hide the submit-button CTA link to reset dates in the mobile
app. They are working on their own solution.
- Don't show the dates_banner.html code in the courseware. It has
new CTA banner support with updated wording.
We support it still, but want to encourage folks to try to define it
as a method, so that in the future, we can rely on it being one.
Also updates lti-consumer to a version that has the value as a
method.
