COTV-3921: Add ability to change VM Name for second and third nodes for HA Deployment
Issue
When deploying HA mode in 10.2 and earlier, the OVF template allows you to provide a hostname. OTV will use that hostname to name the first node name and then append a 2 or 3 to the partner nodes. For example:
den2-naotv1-node1
den2-naotv1-node12
den2-naotv1-node13
