      Description of problem:

          Whenever the annotation hypershift.openshift.io/aws-load-balancer-subnets is set on a HostedCluster (the default in rosa) on a 3-zone management cluster, the AWS vpc endpoint (private link) fails to be created on a hosted cluster that uses 3 zones for its nodes.

      Version-Release number of selected component (if applicable):

          4.20.0 latest nightly

      How reproducible:

          always

      Steps to Reproduce:

          1. Create a management cluster with machines in 3 zones (can be hosted cluster)
          2. Create a PublicAndPrivate HostedCluster with nodepools in 3 zones and annotate it with hypershift.openshift.io/aws-load-balancer-subnets pointing to 2 of the subnets of the management cluster.
          3. Wait for the HostedCluster to come up
          

      Actual results:

          The HostedCluster never finishes provisioning because its VPC endpoint cannot be created.

      Expected results:

          The HostedCluster is created normally
