Title:
  enable AliYun datasource by default

Status in cloud-init:
  Confirmed
Status in cloud-init package in Ubuntu:
  Fix Released
Status in cloud-init source package in Xenial:
  New
Status in cloud-init source package in Zesty:
  New

Bug description:
  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 ?
