Google Cloud Common API client library

google-cloud-common is a foundational Python library that provides generated Python types and common helpers for other Google Cloud client libraries. It is not typically used as a standalone application client but serves as an internal dependency for service-specific client libraries within the `google-cloud-python` ecosystem. The current version is 1.9.0. It is actively maintained as part of the broader Google Cloud Python client libraries, which have a frequent release cadence.
