[src] Upgrade Lightning to 1.x

[mpariente]

Fixed

• configure_optimizers needed to return a dictionary when the scheduler is ReduceLROnPlateau.

Changed

• Use self.log in training and validation step (very practical)

Didn't find out yet

• Logging hyperparams, tried several way.

Before merging

Need to test that the recipes still work.

@JorisCos could you have a look if things are working how you expect them to on your end please?

[JorisCos]

Not very important but is it me or there is something wrong here ?
Why is it written 'loEpoch' before val_losss ?

[JorisCos]

Otherwise, everything looks fine to me !

Yes, it does look weird.

Actually, the distributed_backend has been renamed accelerator (see here), maybe it's more automatized when we use that. I'll have a look.
