Google Cloud Client Libraries for Rust - Retired

This crate has been retired, we recommend you stop using it IMMEDIATELY in favor of google-cloud-api-serviceusage-v1.

We will not fix bugs, or make any improvements to the gcp-sdk-* crates. All development continues under the google-cloud-* prefix, where we do plan to make improvements, continue support, and eventually release 1.0 versions with stable APIs.
