RESTBase caching: Force clients to revalidate purged end points
Most of our purged end points should be re-validated by clients on each view,
so that they make sure to have the latest version before reusing content. This
forces clients to re-validate by setting max-age to 0, and adding
must-revalidate.
This patch also reduces max-age for the related end point to one hour, while
leaving s-maxage at a day. This makes sure that clients get the latest copy
from the CDN every now & then, and reduces the time to clear caches in
emergencies.
