Bug 8853 - In conntrack SNAT , FIB flows are not created for existing
Non-NAPT switch ports.

When a port is added to the VpnDpnList it is not checked whether it is a
first/last port and handle the fib flows.

VpnFootprint service Api is now used to handle the last port and
add/delete the fib flows.
