Ignore node_modules when checking Python quality

Enroll already-existing user to a course via management command.

Our current sandbox provisioning uses a create_user management command,
which creates and enrolls a user into a course. However, for TE-1128, we
will need a way to enroll the same user to multiple courses (which are
dynamic at time of provisioning). Using the existing management
command is no longer feasible for that, so we are using one that accesses
the enrollment API, which is the new standard for new enrollment capabilities.

Installing edx-opaque-keys from PyPI

Locked assets, with their nature of requiring authorization, are not
eligible for caching.
