/**
Executes a multipart POST using the current serializer, the parameters defined and the fileParts defined in the request
Executes a multipart POST to the specified endpoint defined on URLString, including the parameters and bodyParts defined in the request.
This request will be streamed from disk, so it's ideally to be used for large media post uploads.

- parameter URLString: the endpoint to connect
- parameter parameters: the parameters to use on the request
- parameter fileParts: the file parameters that are added to the multipart request
- parameter bodyParts: the body parameters that are added to the multipart request
- parameter requestEnqueued: callback to be called when the fileparts are serialized and request is added to the background session. Defaults to nil
- parameter success: callback to be called on successful request
- parameter failure: callback to be called on failed request
