Google Cloud Meta-Package for Python

The `google-cloud` Python package was historically a meta-package designed to install all client libraries for Google Cloud services. However, it was deprecated in June 2018 and marked as inactive/archived. Users are strongly advised to install individual, product-specific client libraries (e.g., `google-cloud-storage`) rather than this meta-package. Its last released version is 0.34.0, from July 2018.
