Async function that returns a stream.Readable instance that will output
the contents of the given URI.
For caching purposes, you can pass in a stream instance from a previous
getUri() call as a cache: stream option, and if the destination has
not changed since the last time the endpoint was retreived then the callback
will be invoked with an Error object with code set to "ENOTMODIFIED" and
null for the "stream" instance argument. In this case, you can skip
retreiving the file again and continue to use the previous payload.
