In a shared VPC architecture, it is possible to create private hosted zones (private/local) in the cluster creator account instead of the VPC owner account. This requires that the association to the VPC be authorized in the cluster creator account and be performed in the VPC owner account. 

This requires adding a flag `--private-zones-in-cluster-account` to the following commands:

• hypershift create infra aws
• hypershift create iam aws
• hypershift create cluster aws
• hypershift destroy infra aws
• hypershift destroy iam aws
• hypershift destroy cluster aws
