Refactor to something like resourceFromPath

[wulfmann]

It may be worth refactoring some of the recursion you’re follow something like cdk does:

https://github.com/aws/aws-cdk/blob/f44ae607670bccee21dfd390effa7d0e8701efd4/packages/%40aws-cdk/aws-apigateway/lib/resource.ts#L328

The reason we wouldn’t use this method outright is because it forces you to use the default resource options. We could simply refactor our looping to be similar, but with options.

The most appealing piece of this is that it will return the resource if it exists. This might actually allow us to reduce some of the recursion because we don’t need to worry about building each branch sequentially to keep the parent reference.
