Add CentOS support

[webmat]

I've always been a fan of Ubuntu, but these days I need to work on CentOS. And I've come to find good things about it too (e.g. SELinux enabled by default).

Are you interested in having me work on the 3 cookbooks to add support for CentOS and soon Amazon Linux (also in the RedHad family)?

To be clear: I'm doing this. I just want to know if you want to keep your cookbooks Ubuntu-focused or if you're interested in me submitting pull request(s) :-)

@webmat, Yes I'm happy to accept your PRs :)

I'd love to see this myself as well. Perhaps if you guys point me in the right direction I could help.

Ah, I haven't taken the time to submit proper PRs, sorry :-/ But @gotjosh, if you check out my forks of appbox and rackbox, you'll see everything you need in the branch support_centos. There's not much missing: only a few tweaks to package names, iirc.

I've been using those versions for a few months on CentOS successfully. We didn't end up using Amazon Linux much, though. So I can't comment on how well that works.

I have been busy with my day job recently. Sorry if I didn't show enough attention to the project. :)

PRs are definitely welcomed. Just a heads up, I will be setting up a unit test and test-kitchen environment, more documentation, and cleaning up unused features.

Thank you very much @webmat I managed to get everything up and running with your branch. If you're too busy I could submit the pull request with your changes? Is there anything else I'd need to add? Let me know!

[webmat]

Haven't needed anything else so far. Go ahead and submit the PR :-)

I don't know if it is related to CentOS, but I recently tried to run the "rackbox" recipe and apparently it is failing when it tries to run appbox::tmux recipe... it's unable to compile it.
