Talking with Rob, we should include allowing failures on the Travis Docker tests.

I did start working on travis allow_failures for those tests, as the team had discussed, but I hadn't finished figuring out how to handle that correctly (so it only affected those tests) with the matrix build.

Probably not very hard, and I was about to test the way I thought it might work (the docs I found weren't completely clear), the last time I was looking at it. Though I was also planning to handle that change as a separate pr, since I didn't know whether people would end up wanting us to proceed with this one.

Looks like the failing Jenkins PR job is a transient? This EZBake job caused the failure:

btw just fyi there is a ticket for this work, so it might be good to add that to the commit messages: https://tickets.puppetlabs.com/browse/PDB-5485
