Hybrid plumby (#585)

* fix configuration of agent and server to be future proof and plumb in the hybrid client agent

* fixes up the tests, turns off /r/ on api nodes

* fix up defaults for runner nodes

* shove the runner async push code down into agent land to use client

* plumb up async-age

* return full call from async dequeue endpoint, since we're storing a whole
call in the MQ we don't need to worry about caching of app/route [for now]
* fast safe shutdown of dequeue looper in runner / tidying of agent
* nice errors for path not found against /r/, /v1/ or other path not found
* removed some stale TODO in agent
* mq backends are only loud mouths in debug mode now

* update tests

* Add caching to hybrid client

* Fix HTTP error handling in hybrid client.

The type switch was on the value rather than a pointer.

* Gofmt.

* Better caching with a nice caching wrapper

* Remove datastore cache which is now unused

* Don't need to manually wrap interface methods

* Go fmt
