TNL-4102

Resolves conflicts between reverts of pattern library test pages and multi-site comprehensive theming, and the re-introduction of pattern library test pages. Fixes a pipeline rendering test which relied on other tests updating assets. The test now ensures that static assets are available before running.

This reverts commit a796b563.

These are developer only pages, so can not be seen in production
environment. On devstack, you can access these pages in LMS and
Studio at:

    /template/ux/reference/pattern-library-test.html

This is the second attempt to enable the Pattern Library. The
first attempt broke Django Templates and didn't work correctly
with right-to-left styling.

- Update to latest version of watchdog.
- inotify doesn't work on nfs share in devstack. Use polling instead.
- Some editors (vim) do not trigger modify events in their default
  configuration. Rebuild assets on all filesystem changes, and debounce
  when changes happen too quickly.

The previous approach for handling NPM assets was
to symlink them into the static directory. This appeared
to cause trouble with the asset pipeline where the files
in question were not installed and then old versions were
picked up instead.

This change instead copies NPM libraries to a new
static directory so that the pipeline can consume them
as with any other file. This new directory is added to
.gitignore so that the files don't get accidentally
checked in.

This reverts commit 954dae58.

This now correctly migrates and dumps files for both databases.

Run lettuce migrations for both databases

By default, migrations are applied as they always have been. Exporting DISABLE_MIGRATIONS=1 or passing --disable-migrations to Paver commands will create tables directly from apps' models.

edx-django-oauth2-provider is being mistaken for django-oauth2-provider. Making the filter less liberal ensures we properly uninstall django-oauth2-provider once.

Follow up to #11432. This value needs to be incremented to ensure the old package is uninstalled.

New package includes support for client credentials grant.

Sass compilation is no longer dependent on Ruby, so we are
removing its dependencies.

Testsonly will not work currently, because the database flush will
remove some data fixtures. Even when they are loaded at the beginning
of the next test run, there are database corruptions. Instead of
flushing, do not do anything with the database at the end of the
testsonly test run. That way, tests that use dynamic data can be
run many times in a row.
