Closes#1178
This covers the S3 APIs which we directly support - reference
minio/minio/cmd/api-router.go
Any APIs which are marked as 'dummy' internally are considered
'unsupported'
Admin APIs are out of scope here
MinIO API extensions are out of scope as well
We are not doing any detailed reference - just pointing out to S3
