Add ability to create multiple deployments in the same AWS account

[audiodude]

When I try to create a second deployment of the CloudFormation, it seems to die with lots of errors about conflicting names. Perhaps the name of the service could be parameterized, or based off the deployment's name, so this doesn't happen?

The use case is to host two different games for different groups of friends.

I figured out how to do this by just copying the yml file and replacing things that looked like *Name: factorio-* with factorio2-*
