This makes an easier division between pure CentOS
contributions and 'genesis-scripts' type output.
Do so in a manner consistent with how 'real'
operating systems get this added.
Have a genesis edition for confluent os deploy. While the need
for genesis is mitigated and many functions should be available
through pre script, provide a more assured environmennt as a
fallback, if the OS isn't going to be imported or using something
like ESXi.
