> Kubernetes supports to have multiple schedulers in one cluster. Actually, the simplest
way to deploy YuniKorn is to co-exist with the default scheduler. Deployment mode has the
following 3 options
>  # Disable default scheduler and just run YuniKorn.
>  # Run both default scheduler and YuniKorn, but each manages a dedicated set of nodes.
>  # Run both default scheduler and Yunikorn, and they share cluster nodes.
> there is no additional work to support option 1 (current method)
> to support option 2, we only need some small effort, for example, we can leverage taints
and tolerations to isolate some nodes for YuniKorn
> for option 3, there is much more work to do, e.g how to handle shared resources.
