add upsert option to DS.create

[kentcdodds]

My edit and create pages are the same (I think that's relatively common). In there I have this code:

var promise;
if (resource.id) {
  promise = DS.update(resourceType, resource.id, resource);
} else {
  promise = DS.create(resourceType, resource);
}
return promise;

May be cool if this was built in so I could just do:

return DS.createOrUpdate(resourceType, resource);

@kentcdodds How would you feel about an upsert option (default: true) added to the DS.create method. It will delegate to DS.update if attrs[definition.idAttribute] exists.

[kentcdodds]

That sounds great to me...

Looks like this is no longer the default in angular-data or js-data. Was that a conscious decision? If so, could we have an option to globally override this?

[jmdobry]

upsert defaults to true in both angular-data and js-data (but only defaults to true in js-data if it's running in the browser). Pretty much all options can be set globally, per-resource, and in the options during a method call.

I believe there's a bug with upsert, I'm preparing a PR on js-data to demostrate.
