Added interface deletion

[Alopalao]

Closes #191

Summary

Added API request to delete interface DELETE api/kytos/topology/v3/interfaces/00:00:00:00:00:00:00:01:1. After the *.*.switch.interface.deleted event, the interface can be deleted from memory if it is not used.

Local Tests

To delete interface, it needs to be removed from OVS: sudo ip link delete s1-eth4 Also:

• It is inactive and disabled.
• It does not have a link.
• There should not be an installed flow related to the interface (actions output, instructions apply_action and match in_port).

End-to-End Tests

TBA

Yes, I think it can be merged. It is a somewhat basic feature.
