What is an Environment?
I see an Environment as a container for anything that affects the behavior of the Template (kinda like structured parameters).
- So parameters can be written into an environment file or automatically inserted if you pass them on the cli.
- You define any non-default Providers in the Environment
- You can define any extra/non-keystone credentials in the Environment
