Google Cloud IAM gRPC Client Library

The `grpc-google-iam-v1` library provides the low-level gRPC client and Protocol Buffer definitions for interacting with the Google Cloud Identity and Access Management (IAM) API. It handles the underlying gRPC communication and data serialization/deserialization. As per Google's official recommendation, this library is generally not intended for direct use by application developers. Instead, the higher-level, idiomatic Python clients like `google-cloud-iam` (which might delegate to `google-cloud-resource-manager` or `google-cloud-iam-admin` for specific IAM operations) should be used. The current version is 0.14.3, and it's part of the regularly updated google-cloud-python ecosystem.
