DEV: partially bake in env
It may be useful for launcher2 build to bake in some env, allowing for default env to run from a built image. Introduce defaultBakeEnv as a list of env to bake into images. This allows for folks pulling images to not need to mark every env variable, allowing for some convenience in starting images.
