[keyserver] Stop sending http cookies
Summary:
ENG-4747
Depends on D9288
We want to stop sending browser cookies on requests from the keyserver. The only exception is for website-responders where we send back any cookies we get. This is done so that they are updated to httpOnly: false and so older clients that will update to redux cookies can migrate.
Test Plan:
- Check that the migration still works
- Check that the web app still works
- Check that the cookie lifespan is still updated
