[Feature] Support wandb logging and vis training samples

[rentainhe]

TODO

• [x] visualization training samples through tensorboard in DINO by setting model.vis_period=20 which will automatically log training samples each 20 iterations.
• [x] visualization training samples in wandb
• [x] add wandb logging training info

Example

Visualize training samples in tensorboard

• Note that we only visualize top-20 pred boxes in training
