@William-Olson looks like Travis errored? Wanna try to fix it?

[William-Olson]

Travis failed on trying to install an old version of docker-engine (completely unrelated to code changes in this Pull Request).

sudo apt-get -o Dpkg::Options::="--force-confnew" -q -y install docker-engine=1.9.1-0~trusty

...

E: There are problems and -y was used without --force-yes

...

The command "sudo apt-get -o Dpkg::Options::="--force-confnew" -q -y install docker-engine=1.9.1-0~trusty" failed and exited with 100 during .

I was trying to keep this PR at a minimal delta, so I might give it a shot but would probably want to make a seperate PR just for that.

It looks like all the current PRs have failing Travis builds (seems very unstable right now).

Haven't messed with travis for a while now so it might take a good minute to get a fix in there if I do take a whack at it.

If you are antsy about getting a working version of letsencrypt/haproxy images I have some temporary images pushed to docker hub until all the fixes are in place to use this repo again.

willko/letsencrypt
willko/haproxy

Feel free to use those until this repo is back in working condition again.

By the way, this problem should go away in our 0.14.0 release tomorrow.
