re:Improvements to ARM-9

[shawn-sterling]

Hello, I am experimenting with rewriting some of our old modules with the new arm-9 goodies.

I think the default hierarchy should have a ${operatingsystemmajrelease} in there somewhere. I deploy centos 5,6 and soon to be 7 boxes and the information and while a lot of module data can be shared with just the ${osfamily} there is quite a bit that does not quite fit.

I know that I can, and have, setup a custom binder_config.yaml to have the majrelease in there now. But I do think that this is something many people would also use. If you do not think so, feel free to close this issue.

Have a good day.
