Change subject: Set thumbnails varnish TTL to 90 days
......................................................................
Set thumbnails varnish TTL to 90 days
In order to verify whether or not we could have a single caching layer
for thumbnails, we can use the existing setup with Varnish to see if
a longer TTL for thumbnails could achieve an acceptable hit ratio.
Bug: T77697
