Benchmark: GCS C++ JSON vs gRPC Client

This benchmark compares performance between the Google Cloud Storage (GCS) C++ client using the JSON REST API and the gRPC client.

Note: we must set the GOOGLE_APPLICATION_CREDENTIALS env variable to the <path-to-credentials.json> before testing. This makes sure that GCS + GRPC direct-path connectivity is tested as well

Prerequisites

Ensure the following libraries are available on your system:
