Let `gsutil` to support Workload Identity Federation authentications (i.e. GitHub OIDC)

I also had this issue when implementing WIF. The way forward is to use gcloud alpha storage instead.

See this comment for more context.

@IuryAlves Ah, thank you! So gcloud alpha storage is the next major version of Google Cloud Storage CLI and gsutil is no longer activily developed. Hope README describes it.

This seems to be the case. Although I don't think they have feature parity yet.

For my usecase I needed to copy from a bucket to a local path (i.e gcloud alpha storage cp) and it worked.

Hi @gfx and @IuryAlves

Our team does not control the bq or gsutil CLIs. There's nothing we can do in our GitHub Action to add support - the owners of those CLI tools need to add support for WIF. You can file a support ticket or technical deal blocker with Google Cloud support to request this functionality.

As pointed out, there's also the gcloud alpha storage CLI which is under active development which does support WIF, but might not have 100% feature parity with gsutil. Thanks!
