Add 'View Consent' button to dashboard when required

Enterprise customers can require user to agree to Data Sharing Consent
form before they can access a course. We now add it conditionally to
Course Dashboard when it's required so it's apparent to user and they
have a way to revist the consent form if they've previously declined or
the course has not yet started.
