Install aurora scheduler locally

I'm surprised heron-core target does not include Aurora scheduler. Not really sure why.

any idea why? @billonahill @kramasamy

No idea. I wonder why heron-core includes any schedulers. I'd expect them to be distributed separately to reduce bloat and extra unnecessary deps.

One thing to notice is that: scheduler will also be run in server side, for instance, yarn-scheduler in container-0. If we exclude scheduler jars from heron-core, then we need to take care of downloading necessary scheduler jars properly.

But I agree at least heron-core should not contain all different implementations of scheduler.
