When deleting an AWS HostedCluster with endpoint access of type PublicAndPrivate or Private, the VPC endpoint for the HostedCluster is not always cleaned up when the HostedCluster is deleted.

4.18.0    

    Most of the time

    1. Create a HostedCluster on AWS with endpoint access PublicAndPrivate
    2. Wait for the HostedCluster to finish deploying
    3. Delete the HostedCluster by deleting the HostedCluster resource (oc delete hostedcluster/[name] -n clusters)    

    The vpc endpoint and/or the DNS entries in the hypershift.local hosted zone that corresponds to the hosted cluster are not removed.

    The vpc endpoint and DNS entries in the hypershift.local hosted zone are deleted when the hosted cluster is cleaned up.

With current code, the namespace is deleted before the control plane operator finishes cleanup of the VPC endpoint and related DNS entries.
