You can trick Composer to work with Orchestrator right now, but more official solution would be better.

Also, as we've measured in #66 instrumenting each test separately can add 3-5 seconds overhead for each test which can be unacceptable for those who run them frequently (each PR/commit), but we need to actually measure this with Orchestrator.
