Lay the ground work for integration with travis-ci.org

[fintanmm]

Hi all,

What this PR does, is to introduce testing for this formula. Each state within this formula has it's corresponding instance created using travis-ci. The dependencies for this formula are cloned and made available to each instance. The kitchen file contains the necessary pillar data for creating each WordPress site including the db, vhost, etc...
The tests take about 3 to 4 minutes a piece but I think it's worth it.

Let me know what you think.

Regards,
Fintan

Howdy! I've done this technique with several formulas. So, I'll chime in.

kitchen-salt bootstraps a Docker container with Salt, as you probably know. It looks like you are covering many different OSes. Travis CI can be much slower than your laptop or workstation. So, the tests will take more time than you have measured. Travis quits displaying output after 30 minutes and stops running with failure after 50 minutes.

When you start covering more cases, it is likely you will need to optimize the container bootstrap process. I've started this process here and here. Feel free to join or ask me any questions about testing Salt formulas.

Hi @blbradley,

Thanks for the tip, I'll be following this with interest as I other formulas that I want to contribute to.
