Partially update several objects (asynchronously).

@param partialObjects    New values/operations for the objects. Each object must contain an <code>objectID</code>
attribute.
@param createIfNotExists Whether objects should be created if they do not exist already.
@param requestOptions    Request-specific options.
@param completionHandler The listener that will be notified of the request's outcome.
@return A cancellable request.
