Subject: [PATCH] Fix storage class related issues (#5338)

- Update startup banner to print storage class in capitals. This
makes it easier to identify different storage classes available.

- Update response metadata to not send STANDARD storage class.
This is in accordance with AWS S3 behaviour.

- Update minio-go library to bring in storage class related
changes. This is needed to make transparent translation of
storage class headers for Minio S3 Gateway.

+# 适用于与Amazon S3兼容云存储的Minio Go SDK [![Slack](https://slack.minio.io/slack?type=svg)](https://slack.minio.io) [![Sourcegraph](https://sourcegraph.com/github.com/minio/minio-go/-/badge.svg)](https://sourcegraph.com/github.com/minio/minio-go?badge)
+
+Minio Go Client SDK提供了简单的API来访问任何与Amazon S3兼容的对象存储服务。
+
+**支持的云存储:** 
+
+- AWS Signature Version 4
+   - Amazon S3
+   - Minio
+
+- AWS Signature Version 2
+   - Google Cloud Storage (兼容模式)
+   - Openstack Swift + Swift3 middleware
+   - Ceph Object Gateway
+   - Riak CS
+
+本文我们将学习如何安装Minio client SDK，连接到Minio，并提供一下文件上传的示例。对于完整的API以及示例，请参考[Go Client API Reference](https://docs.minio.io/docs/golang-client-api-reference)。
+
+本文假设你已经有 [Go开发环境](https://docs.minio.io/docs/how-to-install-golang)。
+
+## 从Github下载
+```sh
+go get -u github.com/minio/minio-go
+```
+
+## 初始化Minio Client
+Minio client需要以下4个参数来连接与Amazon S3兼容的对象存储。
+
+| 参数  | 描述| 
+| :---         |     :---     |
+| endpoint   | 对象存储服务的URL   | 
+| accessKeyID | Access key是唯一标识你的账户的用户ID。 |   
+| secretAccessKey | Secret key是你账户的密码。 |
+| secure | true代表使用HTTPS |
+
+
+```go
+package main
+
+import (
+	"github.com/minio/minio-go"
+	"log"
+)
+
+func main() {
+	endpoint := "play.minio.io:9000"
+	accessKeyID := "Q3AM3UQ867SPQQA43P2F"
+	secretAccessKey := "zuf+tfteSlswRu7BJ86wekitnifILbZam1KYY3TG"
+	useSSL := true
+
+	// 初使化 minio client对象。
+	minioClient, err := minio.New(endpoint, accessKeyID, secretAccessKey, useSSL)
+	if err != nil {
+		log.Fatalln(err)
+	}
+
+	log.Printf("%#v\n", minioClient) // minioClient初使化成功
+}
+```
+
+## 示例-文件上传
+本示例连接到一个对象存储服务，创建一个存储桶并上传一个文件到存储桶中。
+
+我们在本示例中使用运行在 [https://play.minio.io:9000](https://play.minio.io:9000) 上的Minio服务，你可以用这个服务来开发和测试。示例中的访问凭据是公开的。
+
+### FileUploader.go
+```go

+)

+	secretAccessKey := "zuf+tfteSlswRu7BJ86wekitnifILbZam1KYY3TG"
+	useSSL := true
+
+	// 初使化minio client对象。
+	minioClient, err := minio.New(endpoint, accessKeyID, secretAccessKey, useSSL)
+	if err != nil {
+		log.Fatalln(err)
+	}
+
+	// 创建一个叫mymusic的存储桶。
+	bucketName := "mymusic"
+	location := "us-east-1"
+
+	err = minioClient.MakeBucket(bucketName, location)
+	if err != nil {
+		// 检查存储桶是否已经存在。
+		exists, err := minioClient.BucketExists(bucketName)
+		if err == nil && exists {
+			log.Printf("We already own %s\n", bucketName)
+		} else {
+			log.Fatalln(err)
+		}
+	}
+	log.Printf("Successfully created %s\n", bucketName)
+
+	// 上传一个zip文件。
+	objectName := "golden-oldies.zip"
+	filePath := "/tmp/golden-oldies.zip"
+	contentType := "application/zip"
+
+	// 使用FPutObject上传一个zip文件。
+	n, err := minioClient.FPutObject(bucketName, objectName, filePath, minio.PutObjectOptions{ContentType:contentType})
+	if err != nil {
+		log.Fatalln(err)
+	}
+
+	log.Printf("Successfully uploaded %s of size %d\n", objectName, n)
+}
+```
+
+### 运行FileUploader
+```sh
+go run file-uploader.go
+2016/08/13 17:03:28 Successfully created mymusic 
+2016/08/13 17:03:40 Successfully uploaded golden-oldies.zip of size 16253413
