Optimize kernel neighbour table for large scale environments

Changing the default values of neighbor table (also known as ARP table)
in the kernel to avoid neighbour table overflow and thus fix
communication errors between overcloud nodes.
default kernel values support L2 network up to 1024 hosts (/22).
The patch will allow up to 4096 hosts (/20).
