internal/proxy: cache info and mod endpoints

Add more caching to the proxy client so we can call Info and Mod
multiple times during a fetch without worrying about wasted RPCs to
the proxy.

This will enable moving the load shedder, which requires its own info
call, out of the fetch logic and into the worker.

For golang/go#48010
