Native support for Google cloud storage using the Google Cloud Storage libraries. Authentication is performed using GCS service account credentials JSON. Currently, Milvus supports Google Cloud Storage using S3-compatible APIs via the AWS SDK. This approach has the following limitations: 1. Overhead: Translating requests between S3-compatible APIs and GCS can introduce additional overhead. 2. Compatibility Limitations: Some features of the original S3 API may not fully translate or work as expected with GCS. To address these limitations, This enhancement is needed. Related Issue: #36212
