Write some tests about zookeeper-cookbook

@jakedavis hooking up to do Foodcritic, RuboCop, and ChefSpec testing using Travis is pretty straightforward, but getting a Test Kitchen convergence is a bit trickier. It can be done, however, though it requires using EC2, Digital Ocean, Rackspace, or some other mechanism to actually create the virtual machine for testing, since you can't create a VM on Travis.

Just an FYI on this, since I'm in the middle of wrangling with Travis automation myself for cookbooks.

Good to know. Yeah, I definitely like the more test-based approach. Mostly TK is nice because we kind of promised some CentOS support on this cookbook previously (we're completely Ubuntu). Tests will help mitigate the concerns though :)

We're completely Ubuntu as well, so yeah, if you're looking to promise CentOS, TK is the way to go.
