Can't undeploy link on running lab using Kathara.get_instance().undeploy_link() with the python api about kathara

Hi @BMG-DYNAMIT,

Thanks for opening the issue!

To undeploy a link, first you must undeploy all the devices attached to it.

To disconnect a device from a link, you can use the disconnect_machine_from_link method:

Kathara/src/Kathara/manager/Kathara.py

Lines 108 to 123 in 362ba16

	def disconnect_machine_from_link(self, machine: Machine, link: Link) -> None:
	"""Disconnect a Kathara device from a collision domain.
	Args:
	machine (Kathara.model.Machine): A Kathara machine object.
	link (Kathara.model.Link): The Kathara collision domain from which disconnect the device.
	Returns:
	None
	Raises:
	LabNotFoundError: If the device specified is not associated to any network scenario.
	LabNotFoundError: If the collision domain is not associated to any network scenario.
	MachineCollisionDomainConflictError: If the device is not connected to the collision domain.
	"""
	self.manager.disconnect_machine_from_link(machine, link)

After all the devices connected to the link are disconnected, you can undeploy the link.

We will update the undeploy_link method's documentation to make that clear.

Thanks,
Tommaso
