BUG 8930 - delete Op VPN interface when deleting external network
Op VPNInterafce is removed in VrfEntryListener when the last
adjacency for the VPNInterface is removed.
The problem is VPN interface for external network doesn't
have any adjacency nor VrfEntry.
As a result, when the external Vpn interface is removed
the Op VpnInstance is not removed as it should.
Fix: Delete the Op VPN interface in VpnInterfaceManager
if the VPN interface to be deleted doesn't have any adjacency
