The render_xblock view, which powers the Learning
MFE (among other things) returned a 404 when un-
enrolled course staff users tried to load it while
masquerading as learners. This was because we
checked course access after enabling the
masquerading context, which triggered a redirect-
to-enrollment exception.
The fix is simply to enable the masquerading
context after checking course access.
Content-level behavior and access is still
calculated within the masquerading context,
as intended.

Centralize the logic for choosing between
MFE and Legacy-frontend courseware within
three new functions:
* courseware_mfe_is_active
* courseware_mfe_is_visible
* courseware_legacy_is_visible
This allows us to create another new function:
* get_courseware_url
which can be called anywhere in LMS/Studio
to get the canonical URL to courseware
content (whether it be MFE or Legacy).
In future commits we we begin using
get_courseware_url throughout the platform.

- Move some of the recently added logic from the instructor app to the certificates app
- Attempt to not use other certificate models directly in the code I am touching, moving this logic to certificates as well.
The Django setting
FEATURES['ENABLE_COURSEWARE_MICROFRONTEND']
has been an additional gate to activating
usage of the Learning MFE for an Open edX
instance.
The toggle is redundant with the
`courseware.courseware_mfe`
Waffle flag. By removing it, we simplify our config
and simplify our path towards making the Learning MFE
the default courseware experience.

In preparation for switching LMS/Studio over
from serving legacy courseware URLs in certain
places (for example, resume_course_url) to serving
learning micro-frontend URLs.

Mobile apps load HTML (and other) XBlocks individually using the
render_xblock endpoint. This is an attmept to reduce the number
of requests and JS processing needed to do so by detecting when
we have math content in HTMLBlocks and only adding the Mathjax
resources when necessary.
This is controlled by the "courseware.optimized_render_xblock"
CourseWaffleFlag. For maximum safety, we currently only optimize
in this way when directly hitting HTMLBlocks, and not for
ProblemBlock or VerticalBlock.
This was made as part of edX's Hackathon XXV.
This PR lays the groundwork for a an LTI tab that can embed any LTI1.1-based
tool as an course tab. It also adds another tab based on this LTI Tab that
offers special support for embedding LTI-based discussion tools in a course
tab. If enabled this will replace the existing discussion tab.
There is certain gating logic around pre-reqs, timed exams, etc.
that happen at the SequenceModule level, and should be respected
when rendering descendant XBlocks (like individual problems) that
are in that Sequence. Rather than do a risky refactoring, I'm
keeping that logic where it is and having the render_xblock view
climb up through the ancestor list to call the SequenceModule for
that gating information.
We do _not_ check all descendants (so cousin leaf nodes in the
sequence) for cotent-type-based restrictions because sequences can
become very large (esp. when content libraries are used), and there
is a performance overhead.
If the enclosing sequence is gated in some way, we redirect to the
render_xblock view for that sequence, where hopefully some useful
messaging will be available. This is a stopgap. That redirect
should never happen because we should never be calling the leaf
XBlock for a sequence that is restricted in the MFE. But if somehow
we get there anyway, either by bug or by intrepid user fiddling,
it's better to redirect somewhere that an error _might_ be surfaced
rather than just failing.
This will actually be a little overzealous and lock things down
that should be made visible later. If there's a timed exam and the
exam is completed, it should be the case that content is visible
(just read-only). This commit will block the content before the exam
starts (this is right), open the content while the exam is live
(this is right), but make the content unavailable after the exam
period has finished (this is wrong).
But I am going to go forward with this even knowing it's wrong
because:
1. The render_xblock endpoint should never currently be used in
timed exams in an intentional way. Neither the mobile experience
nor the courseware MFE support it.
2. This fix will address security concerns for creative access
patterns, even if it goes too far.
3. We're going to need to do a lot of work to address both pluggable
access permissions handling and special exams in the courseware
MFE, and a better implementation can be done then.
4. I've had multiple failed attempts to get this to work without
breaking things on and off over the course of weeks, and this
is a relatively low risk way of doing it that doesn't involve
a major refactoring (though the bill for that will come due
when we bring timed exams to the MFE).
Blocks that were hidden by access checks would not be used when
calculating past due status for a unit. This adds in a check to
still look at those blocks, but will maintain not rendering them
when being accessed via the MFE
The change to masquerade in the courseware view allows the proper
viewing of the xblock from the perspective of the masqueraded user.
In this case, it allows a staff user masquerading as a learner to see
their shift dates calls to action inside the MFE (the old view already
had this set up). The second change allows the staff user masquerading
to reset the schedule of the learner being masqueraded via the CTAs
The toggle was previously an ExperimentWaffleFlag,
which allows stable A/B testing but increases the toggle's
complexity. Since we do not plan an doing any more A/B
tests as part of the MFE rollout, we can 'downgrade' this
toggle to a CourseWaffleFlag, which still allows us to do
phased rollout and course-run-specific overrides.
By explicitly importing the legacy namespace classes, we make it clear
that we are using soon-to-be-deprecated classes. We will then be able to
start removing the legacy classes, one module at a time.

This uses the new names introduced in edx-django-utils
3.8.0 (edx/edx-django-utils#59), which we're already using, as
well as updating a few other locations where we incorrectly refer
to New Relic custom metrics instead of custom attributes.
Includes a couple of unrelated lint fixes in a file I modified.
- 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.
This also has an initial use case for Personalized Learner Schedules
to add CTAs to capa and vertical blocks to allow users to shift their
course deadlines.
This reverts commit 06e04eff8c.
Omitting the course_key argument to ExperimentWaffleFlag.is_enabled
causes a 500 when the underlying experiment flag is enabled.

Its ripe for confusion to have this logic split between two separate
methods. This consolidation should make things easier to understand and
hopefully, less issue prone.
We don't really benefit from having two methods here anyway, as one is
_only_ ever called by the other.
It's also misleading that the second helper, in `toggles.py`, _also_
checks the FEATURE flag, as well as the waffle flag.
This switches the Dates Tab to be an enrolled tab allowing only
enrolled learners to view. Additionally, it will now redirect
logged out learners to the login page if they hit the Dates Tab directly.
- yt_video_metadata returned a generic non-json-api-friendly 500 error
when called on a non-youtube video
- load_metadata_from_youtube was crashing when called from the xblock
yt_video_metadata endpoint. It passes a webob request, which has a
different api for retrieving the http referer.
