Something weird happens here, while the local integration test succeeds.
The assert for task ec2_instance_cpu_options : start instance as t3.micro is failing.

• change detection is correct: https://ansible.softwarefactory-project.io/zuul/build/b7904ec9dad14e94869e8ad5bb514757/log/job-output.txt#3953
• but the instance itself, still boots as t3.nano https://ansible.softwarefactory-project.io/zuul/build/b7904ec9dad14e94869e8ad5bb514757/log/job-output.txt#3994

I'm not sure what happens here.
t3.nano and t3.micro should be allowed https://github.com/mattclay/aws-terminator/blob/8512bb30ce115dc00128ff93cbacb6ab48c606b5/aws/policy/compute.yaml#L27-L28

do you have any ideas @tremble
