We can use docker-compose to bring up SO containers in a development environment.

This solution is lighter weight than kubernetes with rancher, and should be a lot easier to use for those who don't need all the management functions provided by kubernetes.

I've included a script that fetches the springboot overlay files (config files) from the oom repo and parameterizes them for the docker-config environment.  This should alleviate the issues we would otherwise have with keeping two sets of overlay files in sync.

Note that nothing here affects any delivered artifact, so perhaps the PTL will consider merging it into casablanca, even though it is past the maintenance release date.
