Move pattern-replacement file lists into a separate file

punt the react stuff for now

This reverts commit 67177ac7.

The original PR cause a breakage on production due to webpack building two different
copies of the asset_index.js bundle. However, it is unclear whether that was a
transitory issue or not. This commit restores the original PR to validate whether
the problem is reproducible.

This reverts commit 1c46bd89, reversing
changes made to eb6064e3.

This reverts commit 4946b6b2.

* Implement a ViewedEvent handling system which calls handlers when a
  block has been viewed for 5 seconds (configurable).
* Hook up Verticals to register their children blocks with this event,
  and submit completions once seen.

Running LMS Karma tests was causing the following error:

  TypeError: modules[moduleId] is undefined
  at /edx/app/edxapp/edx-platform/lms/static/course_experience/js/spec/Enrollment_spec.js:20

The root issue was sinon, as documented here:
  https://github.com/webpack/webpack/issues/304

I tried multiple fixes suggested from that issue until I found one that
worked: https://github.com/webpack/webpack/issues/304#issuecomment-272150177

The user can now enroll in a session, unenroll from a session or change session
from a new course enrollment card on the programs dashboard.

Increase the number of bundles that a chunk has to appear in to be put
into the commons.js bundle. This drastically reduces the size of the
commons.js bundle (used basically everywhere on LMS and Studio) from
953K to 188K, mostly at the cost of making AccessibilityPage and
AssetsPage (both Studio-only) larger -- 345K -> 1.1M, 91K -> 865K.

setting in the common.py file. The reviews tool is Course Talk.
