OpenVPN server option on GNS3 VM

[AJNOURI]

This is related to GNS3/gns3-server#1181

Until a global solution is found for the issue, does it make sense to add openvpn configuration option to GNS3 VM?

• If GNS3 VM is installed on the same local nework, all devices talk to each other, where ever they are installed.

• But, if GNS3 VM is on Public cloud provider with public IP, it cannot reach the private IP of the local host or local server, so nodes not installed on the same place will not talk to each other.
  Hence the idea of openvpn option on GNS3-VM.
