CYFS stack has supported interfaces for NDN download task

After a download task created by get_data or create_trans_task, CYFS stack support following interfaces for it:

• Group tasks with path
• Control state of task or group, start/pause/resume/cancel it
• Query state of task or group, like progress, speed

CYFS stack should support interfaces for NDN upload task

When a dec app based on CYFS stack got interest request for a chunk from a remote download task, if app decides to response chunk's data, a upload task should be created. Similar to interfaces for a download task, app may interact with upload tasks with interfaces:

• Group tasks with path
• Control state of task or group, start/pause/resume/cancel it
• Query state of task or group, like progress, speed

A scene: making a backup for a directory on device to its OOD

In this scene, service running on OOD downloads files from device, app running on device has to display backup progress, speed on user interface;
We only supports interface for download task now, app will implement this scene by shortly polling download task's state from OOD with NON get request;
If interfaces for upload tasks supported, app can implement it simply by shortly polling upload task's state locally;

Hello everyone, I'm not sure if you can help with this or if this is even the right thread but I'm having issues with creating a user interface for a head unit that I'm building. Can anyone help me out with this one?
