Does it make any sense to allow for an optional plugin to be specified for requesting an upstream?
Right now - it doesn't seem like I could think of much reason to request an Upstream from something other than Hostname or prefix, but hmm, it seems like its worth an option in the future?
maybe a user wants to specify upstream via header? X-Use-Header
maybe a user wants to treat clients differently based upon some sort of header? (Maybe there is a beta user header and you'd like to pivot upstreams based upon that?)
