Update test matrix to run faster & add 18.04

[onlyhavecans]

Travis numbers:
Before: Ran for 1 hr 29 min 42 sec
After: Ran for 12 min 12 sec

Using travis' concurrency with separated kitchen instances makes finding errors, parsing the logs, and all general troubleshooting better too.

On both suites it's not the authoritive that is failing now but Postgresql test suite, they are timing out. I did not have this issue when I ran all the 18.04 tests locally but I will run the full suite and see if I can replicate

[onlyhavecans]

The problem is we cannot test installing 40 on 18.04, there is no repo for it. The tests were hiding the problem because they have allow failure on, so things broke later.

[onlyhavecans]

I'm passing all locally now so just waiting for tests to finish in Travis

[onlyhavecans]

Trying to make the test suite faster I enabled concurrent builds for this repo, there is not any resources it needs that should require them. I also broke out all instances so they are easier to see where the failures are. This gives us much more concurrency than the two we originally had

[onlyhavecans]

While we still have the one test failing and timing out at least it runs way faster

Before: Ran for 1 hr 29 min 42 sec
After: Ran for 21 min 1 sec

[martinisoft]

If we're ok with the 18.04 PG test not completing we can either remove it or comment it out with a note.

[onlyhavecans]

I've only removed it in the travis matrix, as the test runs locally without issue

[martinisoft]

Fantastic work! Sooooooo much faster too, I love it!
