Is your feature request related to a problem? Please describe.
All Tensorboard logs are currently saved with TensorboardX. Since version 1.2, PyTorch has received native support via torch.utils.tensorboard.

Describe the solution you'd like
Guided by these two tutorials:

• TORCH.UTILS.TENSORBOARD
• VISUALIZING MODELS, DATA, AND TRAINING WITH TENSORBOARD

it is time to move Catalyst to tensorboard from PyTorch.

After that, in requirements/requirements.txt, increase the minimum version of PyTorch to 1.2.
