feat!: Set the provided SA when creating autopilot clusters

[ferrarimarco]

Fixes #1488

Hi folks!

In this PR, I'm trying to address the above issue, although I think the necessary server-side fix is still being rolled out.

Hopefully I got the autogen bits right :)

If I read the log correctly, the failures reported in https://github.com/terraform-google-modules/terraform-google-kubernetes-engine/pull/1495/checks?check_run_id=9992487427 don't seem too related to this PR, but rather to a checksum mismatch when downloading providers/plugins.

[ferrarimarco]

Ah, so now the build may be failing for that yet missing server-side fix.

It appears to be the case. This is an extract from the Terraform INFO output running in my environment when testing this PR:

2022-12-09T13:53:19.420Z [ERROR] provider.terraform-provider-google-beta_v4.44.1_x5: Response contains error diagnostic: diagnostic_attribute=AttributeName("cluster_autoscaling").ElementKeyInt(0).AttributeName("enabled") @caller=github.com/hashicorp/terraform-plugin-go@v0.10.0/tfprotov5/internal/diag/diagnostics.go:56 diagnostic_detail=""cluster_autoscaling.0.enabled": conflicts with enable_autopilot" diagnostic_summary="Conflicting configuration arguments" @module=sdk.proto diagnostic_severity=ERROR tf_proto_version=5.2 tf_provider_addr=provider tf_req_id=REDACTED tf_resource_type=google_container_cluster tf_rpc=ValidateResourceTypeConfig timestamp=2022-12-09T13:53:19.420Z

[ferrarimarco]

Ah, I was wrongly setting cluster_autoscaling.enabled. Fixed.

Ok, now I think I'm getting the server-side error on a resource update:

I was able to create it anew tho.

Hi @ferrarimarco! Thank you for working on this. is there a GitHub issue or PR I can watch to track the server side fix?

Thanks for the PR @ferrarimarco.
I pushed a few changes as we are switching to a new test framework. Looks like this will be a breaking change as the conflict on the field was removed in 4.44+.

[ferrarimarco]

@CaliWee hi! I don't think there is a PR or issue to follow.

@bharathkkb Thanks for reviewing and for the changes!

Update: Yes, in 4.44+. I forgot to update the provider version constraint, but I see you did it. Thanks!
