Remove "curried" nested resources and manually specified urlParams (#625)

* Drop support for optional url params

* Delete nested resource files

* Remove urlData

* Extract urlParams from path instead of manual definition

Verified this is no different with:

```js
const urlParams = utils.extractUrlParams(spec.path || '');
if (
  !(spec.urlParams || []).every((x, i) => urlParams[i] === x) ||
  (spec.urlParams || []).length !== urlParams.length
) {
  throw Error(
    'mismatch' + JSON.stringify(urlParams) + JSON.stringify(spec.urlParams)
  );
}
```

inside StripeMethod

* Remove manually specified urlParams

* Add a deprecation error message

* Revert "Delete nested resource files"

This reverts commit d88a3e7.

* Fix nested resources for non-curried urlParams and update tests to demonstrate their use

* Refactor makeRequest

* Revert "Revert "Delete nested resource files""

This reverts commit e5eccb8.
