Support for deleted interfaces

[fatman00]

When I am using the "show interfaces" parser the resulting output includes delete subinterfaces but does not show the interfaces as deleted. Gig 0/0/0.2 is the example here where i cannot from the python code see that the interface is in fact deleted on the device.

interfaces = dev.parse('show interfaces')
print(interfaces)

A new key will be added to check the interface status. Thank you, this will be fixed in the next release 22.10.
