feat: add support for pod_range in private cluster

[shubhamkr619]

Trying to support the ticket id #1802. The ticket required to have pod_range to deploy node_pools to a different range from the cluster.

Adding extra support for placement group as well. These features are available in private-cluster-beta and now supported in GA
