This prevents server names from ending with an underscore and blank
Only include environment in server name if set.
Given our conversation this morning, does it make sense to allow pave to run without an environment? Should it default to dev instead? Alternatively, should it just error out if no env is set?
We should make this behaviour consistent between plow and pave.
I'm OK with closing this PR if it doesn't make sense.
This doesn't make sense anymore since we're always setting the environment. Closing.
