As it stands, to opt out of using Get, you must do three things:

1. Use --module mode
2. Update paths.imports to be an empty array
3. Provide your own Request shim

While we believe that using CreateAPI with Get it the quickest and easiest option, we understand that not everybody is in a position to adopt Get. As a result, we need to provide a better way to disable use of the dependency.

Description

I can think of three scenarios:

1. You want to use Get and you are happy with the default behaviour
2. Your networking client already defines it's own Request in a module that should be imported
3. You will build your networking client on top of the generated code and want a Request type generated for you

I did at first think that we should just generate Request if you opted not to use Get, but this will put some people who already import a different module defining Request in a situation where they can't use the generated code. It might be that like Get, the Request type is used for manually crafted requests too so defining it inside the CreateAPI generated package might not be appropriate.

Not sure how best to handle this...
