get_service_account() always cries "warning: etag is deprecated: Deprecated. Do not use."

[lazcamus]

What happened?

any call to iam.v1.get_service_account() will result in a warning "warning: etag is deprecated: Deprecated. Do not use."

The GetServiceAccountResult complains about a non-None value returned from google for etag at

pulumi-google-native/sdk/python/pulumi_google_native/iam/v1/get_service_account.py

Line 38 in 5d84564

pulumi.log.warn("""etag is deprecated: Deprecated. Do not use.""")

There's no way to work around this ... Google is providing the etag in the response

Expected Behavior

It shouldn't warn for something that is outside of the caller's control

Steps to reproduce

Call get_service_account() with any valid arguments and receive a result. Observe the warning in the pulumi log.

I'm using this as a workaround for a gcp-native issue where it's difficult to safely handle lookups of service accounts that don't exist

@lazcamus Thanks for reporting this issue and we apologize for the inconvenience caused by this deprecation message. Unfortunately we're not in a position to actively work on this provider right now as we're focusing on the pulumi-gcp provider while this provider is only in preview mode currently. We'll keep this issue open and on our backlog once we can start working on this.

As a follow-up, the etag field is marked as deprecated by the Google Cloud API (https://cloud.google.com/iam/docs/reference/rest/v1/projects.serviceAccounts#ServiceAccount) which results in us auto-generating the deprecation warning message. We'll need to ensure that the deprecation message only occurs when users specify etag when they create a service account, rather than when listing them.
