Replace caching system with support for http proxy
We currently use a rudimentary caching system we build in lava to avoid downloading the same things over and over. However, there are some issues with this approach, but there's no good reason I can think of to do this ourselves rather than using an existing http proxy such as squid. Lava should default to no caching, but also support using an http proxy if one exists.
