some other fixes and enhancemets to address failures in the IPv6 Scale testing:
- The rate at which VPP sends ARP/ND requests, 1 per-millisecond, is too high. This is reduced to 1 every 10 ms. probably still too high.
- If an ARP/ND response is received that does not contain a change to the known MAC address, no further processing is done.
- Added stats to get info about the async FIB walks.
- When walking FIB entries and performing a load-balance update, it is not necessary to re-insert the LB in the forwarding table.
