Minor Description
Currently we use docker-compose files to run ozone pseudo cluster locally. After a full build, they can be found under hadoop-dist/target/compose.
As they are very useful, I propose to make them part of the ozone release to make it easier to try out ozone locally.
I propose to create a new folder (docker/) in the ozone.tar.gz which contains all the docker-compose subdirectories + some basic README how they could be used.
We should explain in the README that the docker-compose files are not for production just for local experiments.
