Using edx-opaque-keys instead of opaque-keys

ccx-keys has been updated to use the edx-opaque-keys library from PyPI, rather than simply expect the package to be pre-installed. The edx-opaque-keys version has been bumped as it was updated to export test packages needed by ccx-keys.

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.

Update age calculation to be more conservative.

Installing edx-opaque-keys from PyPI

This introduces a mechanism to control the time-to-live for an unlocked

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