feat: add error level flag

[jacobshilitz]

Is your feature request related to a problem? Please describe.
Some carriers return notes and warnings which are not errors, but they can be useful.
for example, FedEx we disabled the "note" type messages because it was not an error, see commit 4d2a07b.

Describe the solution you'd like
Add a level to message object that indicates whether it's an error or just a notice.
and add support for all the carriers

I thought it can maybe also be a setting in the user or in the API in each call, what errors should be suppressed

@danh91 can you give some input on how you would like this to be implemented?

Hi @jacobshilitz,

Yes, adding an optional level field to the Message type is the way to go.

karrio/modules/sdk/karrio/core/models.py

Lines 239 to 246 in 330a6b9

	class Message:
	"""Karrio unified Message data type."""
	carrier_name: str
	carrier_id: str
	message: Union[str, Any] = None
	code: str = None
	details: Dict = None

So that every carrier integration can adopt it progressively on there error parsing functions.

e.g. fedex

pass the level to the Message type

karrio/modules/connectors/fedex/karrio/providers/fedex/error.py

Lines 48 to 62 in 330a6b9

	return [
	models.Message(
	carrier_name=settings.carrier_name,
	carrier_id=settings.carrier_id,
	code=error.get("code"),
	message=error.get("message"),
	details=lib.to_dict(
	{
	**details,
	"tracking_number": error.get("tracking_number"),
	}
	),
	)
	for error in errors
	]

The only thing is we need to standardize the levels with an enum like

class MessageLevelEnum(Enum):
   note
   warning
   error

The enum can be in the sdk/karrio/core/units.py file.

These are the ones I have seen in general. What do you think?
