Title: Add the cleanup when the process of EBS AMI interrupted

Currently we have no cleanup for this scenario: EBS AMI creation interrupted. Although the terminated source instance could avoid this in some degree and the AMI marked as **failed* finally, we still need a normal cleanup for the interruption, which could solve the whole stuff.

Please help review it.
Thanks
Henry
