Moving away from goamz to use minio-go instead. (#4193)
minio-go does fully managed way of handling S3 API requests
- Automatic bucket location management across all s3 regions.
- Transparently upload large files in multipart if file 64MB
or larger.
- Right GetObject() API provides compatibility with
io.ReadWriteSeeker interface.
- Various other APIs including bulk deletes, server side object
copy, bucket policies and bucket notifications.
Fixes #4182
