CLC-4473: UI test for Tele-BEARS appointments

* Verifies the rendering of Tele-BEARS appointments for a set of real users
* Verifies the presence of the appointments on both the My Academics page and on the relevant semester page (if it exists for the user).
* Generates a CSV containing the appointment info for the test users.
Do you really need all the vars above?  Why not remove the line above and then:
 expect(my_academics_page.code_required_icon?).to be true
