[dev] Move specific library requirements into corresponding package folders

[romesco]

e.g. hydra-configs-torchvision for the 0.7 release should require torchvision==0.7, torch==1.6, but other packages like hydra-configs-torch should not depend on torchvision at all.

Make sure noxfile.py is updated to use these new requirements in testing environments.

[romesco]

In the PR for this, also depend on hydra >= 1.1

I was actually questioning the need to depend on any version of torchvision from the conifgs.
There is no direct import of torchvision. I think the reason you are adding it is because you need torchvision when you are creating the configs.

[romesco]

need torchvision for tests.

[omry]

Yeah, using the configs normally requires torchvision. (for tests or otherwise).
