Add initial test-integration suites

Uses go-check in order to separate integration tests into suites, and
have Setup and TearDown operations (on Suites and Tests) ; and use
libcompose to start the external dependencies to test on (like consul,
marathon, etcd, some http images, etc..).

- Update Godeps to get dependencies needed for the use of libcompose
- Setup initial suites and go-check + libcompose mini-framework
- Add some hacks related to libcompose, will be fixed later (when fixed
  upstream)
