deployment-drivers should all create a stack if one does not exist

[EvanBoyle]

Right now, all of the deployment drivers fail if you try to run them on stacks that don't exist in your org. Almost everyone who tries to use them is bound to run into this.

We should add a pre-amble that checks to see if a stack exists before triggering a deploy and creates it via the API if that check 404s.
