WIP: commit to start chefspec being happy
Chefspec is the best spec

This is an inital commit of some generic chefspec
tests for the rabbitmq cookbook. I've tied it up to
the `rake travis` task so when this is merged we can
have it run as part of the PR process.

Again this is just an example and a start, we can attempt
to test the LWRPs at a later date.

Comments are more than welcome.
updated to Chef::ServerRunner
added a check so it traviss slave doesnt write to read a RO location
Updated per @jklare suggestions

I attempted to get the version in object, but i couldn't seem to get it
correct. Any advice or suggestions are more than welcome.

I'd like to merge this ASAP so I can update to 3.4.2 this week.
