Unable to reload/poll for changes from resources

[easen-amp]

Description

Certain resource actions only become available when other actions have completed, e.g. you can only delete an Event once all the Edition's have been unscheduled.

It would be nice to have a method on the resource to reload themselves by a HTTP request using the self HAL link.

await edition.related.unschedule();
await event.related.delete(); // will throw "The delete action is not available, ensure you have permission to perform this action" as the unscheduling is being processed within DC.

Proposal

Option 1

All resources had a reload() method, I could poll until the HAL link is returned...

edition.related.unschedule();

while(!event._links['delete']) {
  event = event.reload(); // <-- new method
}
event.related.delete();

Option 2

Expose a method that poll's DC and returns when the data has changed

edition.related.unschedule();

const updatedEvent = await event.pollForChanges();

updatedEvent.related.delete();
