update fog-aliyun to 0.2.0

Thank you for adding fog-aliyun:0.1.0 in version 9.3.0，I'm using gitlab:9.5.5 now, and when I want to use aliyun-oss to store my backup files, the program always throw exception like:

NameError: undefined local variable or method `access_control_allow_origin' for #Fog::Storage::Aliyun::File:0x00007f0f7c97cfb0

The trace display the file at: /opt/gitlab/embedded/lib/ruby/gems/2.3.0/gems/fog-aliyun-0.1.0/lib/fog/aliyun/models/storage/file.rb:107:in `save'. I guess fog-aliyun:0.2.0 can solve this bug. Can you help me?

When I read file lib/fog/aliyun/models/storage/file.rb at version:0.2.0, the code is very different from 0.1.0

**config **

gitlab_rails['backup_upload_connection'] = {
  'provider' => 'aliyun',
  'aliyun_oss_endpoint' => 'http://oss-cn-shenzhen.aliyuncs.com',
  'aliyun_accesskey_id' => 'xxx',
  'aliyun_accesskey_secret' => 'xxx',
  'aliyun_oss_bucket' => 'mybucket',
  'aliyun_oss_location' => 'oss-cn-shenzhen'
}

gitlab_rails['backup_upload_remote_directory'] = '.' gitlab_rails['backup_multipart_chunk_size'] = 104857600
