title: Ansible: How to stop an EC2 instance started by a different playbook
body: <p>If I start an EC2 instance (or set of instances) in Ansible, how can I later refer to that instance (or set) and terminate them?</p>
  
  <p>This is across playbooks.  So, in one playbook I've already started an instance, then later, I want to terminate those instances with another playbook.</p>
  
  <p>Thanks.</p>
