[S3]Add APIs related to ACL

[mocchira]

Implement APIs related to ACL.

For more details

• API Documents to be implemented
  • references:
    • http://docs.aws.amazon.com/AmazonS3/latest/API/RESTBucketPUT.html
    • http://docs.aws.amazon.com/AmazonS3/latest/API/RESTBucketGETacl.html
    • http://docs.aws.amazon.com/AmazonS3/latest/API/RESTBucketPUTacl.html
  • When calling PUT Bucket, Since SDK users can specify ACLs, we need to modify PUT Bucket
• ACP(Access Control Permissions)
  • Does we need to implement (READ|WRITE)_ACP permissions?
    • reference: http://docs.aws.amazon.com/AmazonS3/latest/dev/ACLOverview.html
  • For now since we can realize minimum necessary features without (READ|WRITE)_ACP permissions, We will not implement (READ|WRITE)_ACP permissions but implement a READ permission including a READ_ACP, a WRITE permission including WRITE_ACP.
• Methods to implement S3ACL
  • XML in a HTTP body
  • eXtended HTTP headers

We will select based on which method is used in each S3SDK( if both of them are used, will implement both ).

Language	Used method(s)
Java	HTTP headers
Ruby	Both of them(depends on sdk users)

Since ruby have used both methods, we need to implement both XML in a HTTP body and eXtended HTTP headers
