Instead of adding new attributes for each cookie name we create
consistent attribute names.  This should prevent any issues where we
have too many different unique attribute names because the cookie names
are unique to the user.

We added two new settings to make the number of cookies and groups
capture configurable:

- TOP_N_COOKIES_CAPTURED
- TOP_N_COOKIE_GROUPS_CAPTURED

Setting a new metric per cookie name resulted in a lot of metrics
getting added to New Relic.  In some cases, this was causing other
more important metrics to not get registered.

We want to be able to easily figure out what our biggest cookies are and we
want to also group cookies by prefix because certain services create multiple
cookies and then put unique identifiers in the cookie name.

For example braze cookie names use the following pattern:
    ab.storage.<userId>
    ab.storage.<deviceId>
    ab.storage.<sessionId>

In this case we want to group all the `ab` cookies together so we can see
their total size.

New attributes:

cookies.<group_prefix>.group.size: The size of a group of cookies. For example
	the sum of the size of all braze cookies would be the value of the
	`cookies.ab.group.size` attribute.
cookies.max.name: The name of the largest cookie sent by the user.
cookies.max.size: The size of the largest cookie sent by the user.
cookies.max.group.name: The name of the largest group of cookies. A single cookie
	counts as a group of one for this calculation.
cookies.max.group.size: The sum total size of all the cookies in the largest group.

Remove py2 requirements.

Fixing test failure due to 31-dec-2020 date issue

The user_tasks app is used by Studio import/export and not used by
anything in the LMS. But because our app-permissions user/role
provisioning script invokes the LMS process, any app+permission
listed there must exist in the LMS or the provisioning fails. So
this commit adds the user_tasks app to the LMS list of installed
apps because it's a lot faster than getting app-permissions to do
the right thing.

  Add is_enabled helper for discussions plugins

In the edx.org-next theme, the completion green check-
marks and the little bookmark icons were appearing on every
single unit. This was because a fontawesome CSS rule
in the new theme was overriding the `display: none`,
as set by `.is-hidden`, to be `display: inline: block`.

The fix is to add `!important` to a couple definitions
of `.is-hidden`. Definitely somewhat hacky, but this is
SCSS that we plan to deprecate at some point anyway.

We seperated base and py35 as a part of the upgrade to python 3 so
that we could get newer versions of some requirements during that
upgrade.  This change is the first step in removing the old requirements
files that were only relevant to python 2.

We leave the python version centric named files instead of base because
we'll need to bump the version of this file regularly and clearly
indicating what version of python it's for makes it easier to reason
about.

Sets default X-Frame-Options for login and registration forms to environment setting

Commit 7f59688f attempted to solve this using
`CourseOverview.course_exists`, but that check is case-
insensitive. This commit instead does a small refactor
to `lms.djangoapps.courseware.get_course` so that we can
handle a failed course lookup without broadly catching
a `ValueError`.
