Should this set `api = new BrooklynApi(...)` in setup, instead of as field? Then can ask the server we've started for what its port is (in case 8081 was left open by some earlier test/process, so we don't fail this test).

Also, I'd mark it as `@BeforeClass(alwaysRun=true)` in case someone comes along and adds a test as live or non-integration (currently in the IDE I think it would pass as it doesn't always respect the groups, but on the command line such a new method would fail).
