redux-resource-fetch

Assuming #275 isn't closed in favor of #250, I should figure out the API for redux-resource-fetch, making the assumption that AbortController is supported.

The popular GitHub fetch polyfill may soon support this: https://github.com/github/fetch/issues/547

---

One possibility based on #275 :

```js
// There is now only one method!
// The first argument determines which CRUD action it is
crudRequest('read', {
url: '/pasta/pls',

// These are options to configure the XHR request
fetchOptions: {
credentials: 'include',
signal: abortController.signal
},

// These are properties that are merged into the start and end action by default
actionProperties: {
resourceName: 'books',
mergeMeta: false
},

// same as what exists today
transformData(data) {
return body.data;
}
})
.then(
(action, body) => dispatch(action)
(action, err) => dispatch(action)
);
```

Start by reviewing the related proposals in issues #275 and #250, then compare them with the existing redux-resource-fetch API referenced as “what exists today.” Confirm the AbortController and fetchOptions assumptions and define an agreed API; the work is done when the API design is settled and implemented consistently.
