Glad to see this work reaching maturity. As Markus noted I think there could be more convergence
down the line too. 

Looking forward to the PR.

with small form factor compute nodes (e.g., IoT gateways). The proposition is to get rid of
Kafka, have controller and invoker compiled together into a "lean" controller-invoker (have
a Gradle project for that) with controller calling the invoker's method directly via an in-memory
object (a queue, which is also loaded via SPI) via a new pluggable load balancer that is selected
via SPI using configuration file property setting. Here is a blog
some more detail and points to our fork.

everything downstream by virtue of exploiting SPI.
