find some other patterns for doing the confirmation/configuration step for generating sublayer components

[swerner]

We have these confirmation steps in the generator commands in the cli that feel pretty clunky after you've already confirmed them...trying to come up with some ideas for ways to skip over those after a while...

[swerner]

Maybe environment variables? We have #73 for adding dotenv and a .env.sample file to the templates, maybe there are some configs we can have there? I don't necessarily need to confirm the api usage each time, but I may want to use different models to see what they come up with. May also be able to add a flag to the command for different behavior?
