Create task builder

[sureshHARDIYA]

Create a task builder using https://github.com/atlassian/react-beautiful-dnd.

We can remove the tab and we can have the following Draggable a) Document, b) Audio, c) Video, d) Assessment (Later).

We already have the Draggable implemented, so, I think, it should be easy to blend in.
