Task model enrichment

[musketeer-eng-team]

Summary

Add this information at task level:
- task description
- the name of the task owner
- the POM
- algorithm name
- the quorum
- a “rewards” field to define how the task is rewarded
- a “datasets” field to define the topology and dataset description to be used
- the number or list of participants who have joined the task

Justification

Add useful information for the user who wants to join a task. All of this information should be set by the task creator.

"Must have" functionality

All of these information are stored during the task creation and retrievable by any user (ffl.get_tasks() method); some information may only be retrievable by the task creator.

A JSON model example (we can further discuss about some of this information):
