Use fed-pydeseq2 logging utils written by @umarteauowkin to log all training quantities that are exchanged in nice graphs and tables.

Hey @umarteauowkin,
Thanks again a billion times for providing those utils. Do you mind checking that everything is okay for you before merge ?
Notably regarding credit assignment.
Cheers.

Thanks for the great work! Just a minor comment, is it possible to add a piece of test for the added components?

Unfortunately we won't be able to do explicit testings. Implicit testing works to the extents that I tested all FL algorithms which produce correct graphs and tables. As the goal of this util is really for power users I don't mind that it can break if some other FL algos are developed. Monitoring is orthogonal to algorithmic functionalities which themselves should be properly tested.

However I cannot merge it as it is right now because of the immense overhead it adds (CI goes up to like 4 hours). I am trying to find a way to cancel every monitoring by default so that most users don't have to face the consequences.

From my perspective (credit assignent), LGTM ! Thanks @jeandut :)
