Add integration/acceptance tests

[tmatilai]

Would be great to have some automated way of testing that the plugin is working as expected. At least to verify that the generated configuration matches expectations, but maybe even trying to validate that it has the wanted effect.

@tmatilai Sorry, I've completely forgot about this :P So I've been thinking about using Bats for that kind of stuff but I haven't tried anything yet. The idea would be to fire up a VBox VM and run Bats tests against a vagrant-lxc VM to check for the expected behavior.

BTW, on vagrant-lxc itself I'm doing some sanity checks using vagrant internals but I'm not sure that is the best approach and some people might even consider it an integration test rather than acceptance.

@fgrehm no probs. I'm visiting Finland/Europe for a month and it seems I don't have time for OSS projects at all. :/

I've used Bats with Test Kitchen and it's nice and simple. Actually I have been thinking that the Test Kitchen itself could be really good fit for all this, at least when the Chef dependency is removed. With it we could spin up the VMs in parallel and run bats (or what ever) test suites on them.

@tmatilai no worries! free to ping me once you get to this ;)
