Pathlib Path instances in a dataclass do not get tracked by task.connect()

[thepycoder]

Describe the bug

Having a Pathlib Path as a variable in a dataclass and then calling Task.connect on it will not report the variable under the configuration section at all.

Perhaps it is worth thinking about which types we can still include as long as they are reasonable to cast to a string. I expect the difficulty will come when changing this value and rerunning the experiment?

To reproduce

Example:

@dataclass
class SingleModeClassifierConfig:
    commit: str = COMMIT  # Commit of the particle extraction to use
    root_folder: Path = ROOT_FOLDER

If in this case one does task.connect(SingleModeClassifierConfig()) the root_folder parameter will not be found under the configuration section. Probably ClearML does not find a way to turn it into a string?

Expected behaviour

The variable to be logged as a string
