UI to visualize retrieval tasks

[sduenas]

We need an interface to visualize which tasks and jobs are running, so the admins of the platform can have a better picture of what data the platform is fetching every moment. Also, it will be useful to see which tasks failed and what the problem was.

The UI should allow to cancel or retry tasks when needed.
