Looks good to me; can we add any unit tests or integ tests that will catch changes like this in the future? Maybe if we modify one of the LB web service integ tests that involve env overrides?

I think we should refactor cli package since svc package, job deploy and svc deploy share some similar processing.

I'm not sure if the current integ test would be a great place to test this. From my understanding the purpose of the stack integ test is to see if the manifest spits out by cli can be transformed into a stack template as expected; however, ApplyEnv happens within cli.
