Overcloud deploy fails when deploying to VMware VM's using vlans.

Issue

• $ sudo journalctl -u os-collect-config on the overcloud-compute shows failure to ping between vlans on the tenant network, possibly other networks as well.
• Vlans are not configured on the VMware virtual switches, so traffic is passed.
