feat!: Remove Paver

BREAKING CHANGE: Removes all remaining Paver commands including
`pavelib/prereqs.py:*` and `pavelib/assets.py:*`.

BREAKING CHANGE: Removes `./manage.py [lms|cms] compile_sass`, which
was just a wrapper around Paver commands.

BREAKING CHANGE: Removes paver.txt. Operators should install testing.txt
instead.

 =============
 
 Django command to output a single Django setting.
-Useful when paver or a shell script needs such a value.
+Originally used by "paver" scripts before we removed them.
+Still useful when a shell script needs such a value.
+Keep in mind that the LMS/CMS startup time is slow, so if you invoke this
+Django management multiple times in a command that gets run often, you are
+going to be sad.
 
 This handles the one specific use case of the "print_settings" command from
 django-extensions that we were actually using.
