Platform: Alibabacloud

#Please specify the platform type: aws, libvirt, openstack or baremetal etc.

Please specify: IPI

What happened?
Not all zone IDs are connected using "-", such as the availability zone ID ap-southeast-6a, and the ap-southeast-6 is region ID.

So removing the prefix via "<region id>-" may fail

What did you expect to happen?
The format of name is fixed, such as: <cluster ID><role><zoone ID>
