In some environments, the origin HTTP resources are easily & quickly accessible
and there is no need for mod_pagespeed to cache them; it's fine to fetch them
whenever they are needed again (say to optimize an image as both a jpeg and a
webp).
In other environments, there is a good cache between the MPS server and the
user (e.g. Varnish) and there's no need to have a cache in MPS either.
So we should have an option to disable caching either of those.
Note that we already refrain from caching output resources in extend_cache, and
from caching input resources when using LoadFromFile, but this option would
cover the rest of the cases.
