TODOs

pass in app properties like -environment=dev jar running inside docker
version docker images

~~2) add typesafe config to read intent-names~~

~~3) expose client-api as a chat-server-client.jar (to maven not ivy), make sure it can be used as sbt deps - https://github.com/duwamish-os/chat-server-api-client~~

provide http-client for API
logging
add swagger
Websocket - https://github.com/finagle/finagle-websocket
don't create jar for root
