Currently, to deploy OSD in the GCP project, constraints/compute.vmExternalIpAccess is one of the GCP organizational policy constraints that cannot be in place. This is because the bootstrap VM need public IPs. With a full support for GCP Private Service Connect and the associated benefit of deploying a private OSD-GCP cluster, this constraint can be relaxed. 

This is a placeholder ticket for investigating HIVE changes required to support OSD clusters in GCP without any public IPs and relaxing constraints/compute.vmExternalIpAccess
