[Catalog] Toggle enrollment to close if enrollment end date has passed

[rpsloan]

Problem statement:

Currently, when an enrollment end date is applied to a listing and this date has passed, it still lists that listing as Open for Enrollment (with the toggle enabled). When viewing the listings page, listings with an end date that has already pass still shows as enrollable. The admin would have to go in each listing to disable the enrollment toggle.

Proposed solution:

When the course enrollment date passes, a listing's Open for Enrollment toggle should switch to OFF. This will allow admins to better identify which listings are enrollable or not from the Listings page.

User role(s):

admin
