Feature: Jenkins for DU image building

[Devdatta Kulkarni]

Currently we are using custom shell scripts for building DUs.

As part of this feature we want to investigate use of Jenkins for the same purpose.

The logical approach is to start with Ed's generic RPC-based builder code and add a 'Jenkins handler'. We would need to run a Jenkins server somewhere (devstack?) and move the builder scripts there. The server would need to be triggered via RPC messages with sufficient information to perform the builds.

A simpler option might be to start with the builder API and let it call Jenkins (synchronously). Once this piece is working move it behind the RPC-based builder code.

Lets not use rpc servers if we don't need them.

Jenkins should be an option, but should not be the default option. Solum should be able to stand alone with a default reference implementation that does not rely on a Java runtime environment.

Drone could be a good alternative. It is a Travis-like CI system built on top of Docker.
More flexible and lighter than jenkins
