Standardize the resource loading status names between helper selectors and ResourceLoader components

Feature Request

Is your feature request related to a problem? Please describe.
The status selectors from the URM resource helper are named differently than the status properties returned from the ResourceLoader components.

The URM helper selectors are using the redux-saga-thunk naming (i.e pending, rejected, fulfilled and done) for status selectors. These match the naming convention of the underlying library used redux-saga-thunk. Here is example code of the status selectors returned from a resource helper.

// NOTE the selector names
const { pending, rejected, fulfilled, done } = resourceListRead('demo').selectors;

The ResourceLoader components return a status object with properties initial, loading, error, and success`. Here is example code showing the status object returned to the render prop a ResourceLoader component:

const DemoListLoader = () => (
  <ResourceListLoader resource="demo" autoLoad>
    // NOTE the status names names
    {({status: { loading, error, success, done }) => (
      <div>Load status example</div>
    )}
  </ResourceListLoader>
);

Describe the solution you'd like
I prefer the naming used in the ResourceLoader components so I suggest we update the resource helpers to return selectors renamed to match. The selectors would be renamed:

Current	Renamed
pending	loading
rejected	error
fulfilled	success
done	done

// suggested updated selector names
const { loading, error, success, done } = resourceListRead('demo').selectors;

Describe alternatives you've considered
Alternatively we could rename the ResourceLoader components status object. I prefer the ResourceLoader status names to the redux-saga-thunk names. They are more clear imo.
