* feat!: Removing the long-deprecated legacy course_modes chooser `course_modes/choose.html` (and its corresponding `_upgrade_button.html`) were specifically only used for the edge case where an enterprise user found themselves in the non-enterprise learner dashboard, and attempted to enroll in a course outside of the enterprise flow. Once upon a time, in a 2U-only workflow, the commerce system would apply specific discounts for users within the said case. That's no longer true, and it has never been true outside of this one company. Removing this template cleans up a legacy version of a legacy page that was, realistically, exclusively seen by employees of 2U, and nobody else. Removes: * The corresponding testsfor behavior only seen in the legacy page. * A waffle flag since all cases route as if the flag is set: `VALUE_PROP_TRACK_SELECTION_FLAG`: `course_modes.use_new_track_selection` * Some variables set in `CourseModeView` which were only ever rendered in the legacy template (`title_content`, `has_credit_upsell`) have been removed from the class. * There is a high likelihood that the class is still a target for re-factoring now that the legacy view is gone, but I'm hesitant to touch something which is not covered by previously existing tests, because the logic around what template gets rendered when is complex.
