Add option to pass args to tracker initialization

[SimonLarsen]

Could be as simple as adding a new field tracker_kwargs that is added to init_kwargs when calling Accelerator.init_trackers.

frogbox/frogbox/pipelines/pipeline.py

Lines 97 to 100 in edb9d71

	init_kwargs={
	"wandb": {"name": self.run_name},
	"mlflow": {"run_name": self.run_name}
	},

This solution does not work if we want to support multiple trackers at once in the future.
