Add some links to student records

Add some waffle-guarded connection points to the Credentials service
to start filling out the user flow for Student Records.

Specifically, add a button to the Program Progress Details page if
a certificate exists, and add a link in the Learner Profile page.

Both only appear if the 'student_records' waffle switch is active.
