No recent cloud-image uploaded to AWS China Regions

[D Zhang]

Currently, cloud image for disco and bionic are several month old in both cn-north-1 and cn-northwest-1 regions.

Image for xenial does not even exist in cn-northwest-1.

Verifiable from https://cloud-images.ubuntu.com/locator/ec2/

Hi,

Thank you for filing this bug.

Images do exist in both cn-north-1 and cn-northwest-1 but are currently not present in the locator.

You can use the aws-cli (https://snapcraft.io/aws-cli) to query the AMI details

```
aws --profile=aws-cn --region cn-northwest-1 ec2 describe-images --owners 837727238323 --filters Name=root-device-type,Values=ebs Name=architecture,Values=x86_64 Name=name,Values='*hvm-ssd/ubuntu-xenial-16.04*' --query 'sort_by(Images, &Name)[-1]'
```

```
aws --profile=aws-cn --region cn-north-1 ec2 describe-images --owners 837727238323 --filters Name=root-device-type,Values=ebs Name=architecture,Values=x86_64 Name=name,Values='*hvm-ssd/ubuntu-xenial-16.04*' --query 'sort_by(Images, &Name)[-1]'
```

We are working on updating the locator tool.
