Unable to add new compute nodes after OpenStack 13 to 16.x upgrade due to NIC naming

Issue

• After an upgrade from OpenStack 13 to 16.x, compute nodes use older RHEL7 NIC names as a result of the LEAPP upgrade.
• New nodes with identical hardware will use default RHEL8 names for NICs .
• For example, an upgraded compute node will use the RHEL7 NIC name such as enp55s1f0, but a new, identical node will use the name enp55s1f8 for the same NIC.
• The OpenStack deployment configuration ("templates") use explicit interface names in the NIC configs.
• If OpenStack templates are updated with the NIC names for the new nodes, then existing compute nodes will fail network configuration, resulting in nodes that will not boot.
