描述

Looking up all Amazon-owned AMIs takes dozens of seconds for me. Even though I know the exact name of the AMI I want, the ami lookup still loads all of them and filters by regex. It should be possible to easily specify a non-regex filter that will passed-through to the API call directly.

研究方向
Examine the current AMI lookup implementation in stacker, likely in the lookup module, to understand how it currently fetches AMIs and applies regex filtering. Consider adding a new parameter such as 'name exact' that uses the DescribeImages API with a filter by name for faster lookup. Check the AWS EC2 DescribeImages documentation for supported filters.
