[Question] Using an IPV4_IPV6 stack type with compute instances

[codesue]

SUMMARY

I would like to create a compute instance that uses an existing dual stack subnet, and I would like to be able to ssh into the machine using the IPV6 address. I've tried simply adding the existing subnet to the machine's network_interfaces using the subnet's selfLink, but when I do that, only the IPV4 address is listed on the machine. The access_config options seem rather limited, and I haven't figured out how to create a compute instance with an IPV4_IPV6 stack type with them. Is this supported? If so, do you have examples of how to do this?

ADDITIONAL INFORMATION

I think the config option of stack-type=IPV4_IPV6 is missing. I'm not sure if this would address this, but wonder if setting an instance template with IPV6 support would allow you to get past this limitation?

I created a PR for this feature. This seems to work when I tested it against GCP locally. #638

Additionally, this branch: https://github.com/safaci2000/google.cloud/tree/feature/computeV6 has more changes that I needed to use personally to assign a static IPV6 address.

I'm not super familiar with the layout of this project, but this change worked for me.

I'd like to see if there's a blocker in getting the MR merged in or if there's anything I could do to help get that merged in. Thank you.
