Title: Feature flagged enrollment counts on instructor dashboard.

* DISPLAY_ANALYTICS_ENROLLMENTS feature flag shows or hides the enrollments counts in the instructor dashboard and legacy dashboard.
* Message directing users to Insights is displayed if DISPLAY_ANALYTICS_ENROLLMENTS is set to false and a ANALYTICS_DASHBOARD_URL is provided.
* Enrollment counts removed from legacy dashboard.

*Legacy Dashboard Enrollments Off*
