Bug description:
  === Begin SRU Template ===
  [Impact]
  Ubuntu cloud-images do not identify the Aliyun cloud platform.
  Until this change was put in place, they would fail to boot and consume
  user-data or metadata there.

  With the change in place, an official Ubuntu image from
  http://cloud-images.ubuntu.com will work properly on Aliyun.

  [Test Case]
  The ideal test case is:
  a.) download a cloud image, update its cloud-init
      The tool 'get-proposed-cloudimg' [1] can be used to do this.

      [1] https://git.launchpad.net/~smoser/cloud-init/+git/sru-
  info/tree/bin/get-proposed-cloudimg

  b.) publish that image to Aliyun cloud
  c.) boot an instance from that image.
  d.) verify function by ssh in verifying /run/cloud-init/result.json shows
      that aliyun datasource was used.

  Ideally post /var/log/cloud-init.log as an attachment to this bug.

  [Regression Potential]
  Generally small chance for regression, but a regression would most likely
  be seen as an attempt to hit the metadata service at the well known end point
  http://100.100.100.200.

  This should be fairly well confined as attempts to use the Aliyun datasource
  are gated by '_is_aliyun_' which does verifies that the dmi product name is
  "Alibaba Cloud ECS"

  [Other Info]

  === End SRU Template ===

  
  As discussed at [1], the addition of AliYun datasource did not enable it by default.
  This is because it has no definitive check before polling the network for data.

  Lawrence suggested he has a solution for this:
   | in our cloud platform, an instance vm could use an asm
   | instructions `cpuid` (with eax setted to 0x40000100 ), it will
   | returned our platform id keyword "AliYun" into register ebx and ecx,
   | and if vm is not running on our environment, the value is others. so I
   | guess this is a method to identify our platform ?
