Add a sample script that can be used to build a test environment

It can be difficult to figure out what to install to get a test
environment that can be used to test all the opportunistic tests,
zookeeper and mysql (with the right user and password and test
database).

This script provides a way to do this on rhel/ubuntu based
environments and can be used to examine how to do this for other
environment types.

I use it with nova boot (on rhel images) and it has worked out
great as a way to rebuild a clean test environment as I need.
