Title: Stdin discovery plugin

As discussed, this branch adds a stdin discovery plugin which can be fed a list of identities, or a JSON rpc output. This also changes the mco rpc agent over to use that discovery plugin for data given on STDIN when not a tty (allowing backwards compatible JSON chaining).

Is this something like what you were thinking of?
