Crate cache

A general purpose cache with possibly multiple remote servers for storing and retrieving data.

The cache includes both type-mapped and namespaced APIs. Caching can be done in-memory or persistently via a cache server that manages a filesystem cache. The cache also supports caching across several cache servers.
