vsphere-iso waiting for ipv6 SSH - need to force ipv4 #9360
Description
When building VMs on vSphere, the API reports an array of IP addresses which come in random order including both ipv4 and ipv6 addresses in the same array. Packer only picks one which may be the ipv6 address in environments that have no ipv6 connectivity.
packer build -var-file ../lab-vars.json ubu-20.json

Build 'vsphere-iso' errored: Timeout waiting for SSH.
During the time that packer is waiting, I can connect via SSH over ipv4 without any issues. The same problem has already been handled in the Openstack builder:
ssh_ip_version (string) - The IP version to use for SSH connections, valid values are 4 and 6. Useful on dual stacked instances where the default behavior is to connect via whichever IP address is returned first from the OpenStack API.
If this option could be ported over to the sphere-iso builder that should solve this problem.
