Secondly, I don't necessarily like the idea of `ResourceIsolationInterface`
taking up responsibility for starting and stopping workers.. This would be
moving a lot of responsibility from supervisor to `ResourceIsolationInterface`
specially when we do a lot of setting-up/tearing-down for worker and use
worker-launcher in multitenant cases. I would have simple interface which may
help us call from within supervisor - and possibly more than once..- without
any side-effects so that we may call them again in case of partial failures.
```
public interface ResourceAllocationInterface {
boolean reserveResourcesForWorker(workerid, resources);
boolean releaseResourcesForWorker(workerid);
```
