Stateful Instance Group policy external/internal ips accepts Mapping[str, str] and not str

[Tahvok]

This affects compute instance groups beta and alpha.

There is an input class StatefulPolicyPreservedStateArgs and an output class StatefulPolicyPreservedStateResponse
They have two optional parameters external_ips and internal_ips. Currently they wrongly assume that they accept a Mapping[str, str].
However, that is wrong. It should be Mapping[str, Mapping[str, str]] (the second value is a map of str ,str).
Or even better, the second value should be a class of its own that accepts an auto_delete parameter.
See here on how to set it properly:
https://cloud.google.com/compute/docs/instance-groups/configuring-stateful-ip-addresses-in-migs#configuring_stateful_ip_addresses_on_mig_creation

From what I understand, both of this files (outputs.py and _inputs.py) are generated somehow - but I couldn't figure out how, so didn't submit a pr with my fix.
I applied the fix manually to make it work, and it works as intended.

Hi @Tahvok - thank you for filing this issue!

I believe (and @danielrbradley can correct me if I'm wrong) that all code gen lives in https://github.com/pulumi/pulumi-google-native/blob/master/provider/pkg/gen/schema.go. We're still finalizing this provider, so I apologize for the lack of information on how to get started contributing.

I'd love it if you wanted to open a fix for this and we're happy to help.
