v1.9.2-rc.1

In v1.9.2 the plugin provides a workaround for the compatibility issues we saw on non-AWS S3 object storage with checksum.
The user may set the checksumAlgorithm as empty string in the BSL, to skip adding checksum to the request header.

All changes

• Bump the version of Golang and protobuf(#198, @ywk253100)
• configuration for checksum algorithm for PutObject to S3 (#197, @reasonerjt)
