(MAINT)(gh-210) series of commits to get beaker smoketest working in ec2

- updates to aws_sdk hypervisor support to correctly use vmhostname, hostname and ip
- additional open ports for ec2 instances
- updates to dsl 'on' method to properly handle additional environment variables
We've had trouble with this in the past I recall, I'm guessing you've already tested this against PuppetDB on EC2?
