Spring Cloud Config External config with Google Cloud Storage(GCS)

Is your feature request related to a problem? Please describe.

Currently, Amazon S3 is supported for external config provider. But Google Cloud Storage(GCS) is not supported yet and I couldn't find any previous discussions.

Is there a plan to support GCS too? As a Google Cloud Platform(GCP) user, it will be great if the Spring Cloud Config supports it.

Describe the solution you'd like

Support GCS.

Describe alternatives you've considered

Now, I'm using Hashicorp Vault on GKE because I can't use Amazon S3. I've considered Redis(Cloud Memorystore for Redis) but GCS is much more simple.
