Merge lp://staging/~canonical-platform-qa/qa-jenkins-jobs/snappy-integration-tests-experimental into lp://staging/qa-jenkins-jobs

When I try to run it locally (without the proxy line [aside: at some point, maybe we should have a way of declaring that automatically across all jobs in the lab that doesn't interfere with running jobs at home?]) I get this:
+ go run integration-tests/main.go

One diff question also.

Going to revisit this when I've worked through whatever firewall blockers thanks for the early review regardless!

Definitely want to keep it in $WORKSPACE. I actually just used $WORKSPACE as $GOPATH in my early tests, but if there's any reason not to, that's fine by me, I just did some double takes because my outside-of-jenkins testing workspace is ~/workspace.d so I had things in ~/workspace.d/workspace.d which looked like a mistake, but wasn't.
