Add support for AWS Auto Scaling (AS) to Ansible’s EC2 dynamic inventory.

This includes inventory groups for AS instances by AS group, by Launch Config, by health status and by lifecycle state. For example, to limit a playbook to instances in the AS group "production":

    ansible-playbook -l as_group_production myplaybook.yml
