ci(kitchen): use pre-salted images instead

[myii]

@javierbertoli has prepared pre-salted images, which run much faster. This WIP PR implements these for CI testing instead.

---

• Confirm this implementation is OK -- updated from @javierbertoli's gist linked below.
• Remove all udev installations from provision_command once the images have that installed.
• Decide what to do about centos-6.

@myii , fixed the scripts, added the missing deps and uploaded new images.

I left here cleaned up kitchen.yml and .travis.yml files, merging what you did here and what I was prepraring. I tested them locally and they 'work for me' (TM) 😋

Regarding centos-6, as I was building locally, I cannot test it due to the vsyscall issue.

But when the packer scripts are ready to build working images, I don't see why not to build the 'complete' matrix (os * os_version * salt_version * python_version) that 'makes sense'? We can discuss this in the irc/slack channels, wdyt?

@javierbertoli Great work! So it should be pulling the new images automatically, right? Nothing else needs configuring here, does it?

The link you've provided ends in a 404 -- do you have an updated link?

Oh dear, Travis isn't going to like you! But that sounds very interesting indeed. Look forward to these discussions.

Sorry, the correct link is to the gist is https://gist.github.com/javierbertoli/2475fb8ba1ffeffcde62226357694e7a

Much cleaner implementation in the gist so I've used that as the commit instead, authored by @javierbertoli. Just going to confirm that the final tests are successful and then I'll merge this.

LGTM :)

One remark (the same as before I think): how to we industrialize creation of images? Are those run on travis? Is the code to generate them available in the saltstack github org? ...

[myii]

@daks I may be wrong but I believe @javierbertoli intends to share the scripts and even maybe have these within the organisation itself.

I found the repo digging in slack backlog https://github.com/netmanagers/salt-image-builder/blob/master/salt-testing-docker.json :)

Good work @javierbertoli and thanks for the review and merge @daks!
