Redeployment to a loadbalanced beanstalk environment that was created with the 1.0 version of the CLI fails with this branch. I'm getting the following serialization error.

Be sure to do lots of redeployment testing from environments created before this change. This has to be a seamless update for users.

Other then my redeployment concerns the changes to the Recipes and CDK projects look good. I did not get a chance to review the orchestrator/typehint code.
