tools: Allow deleting of interfaces

The frr-reload script currently deletes configurations line-by-line under an interface context, if the interface was removed. This approach fails when the interface has already been removed from the system. This change enables whole interface removal using a single command (no interface <interface-name>), simplifying the reload process and reducing reload errors.
