On Tor scale setup, dhcp fails for endpoints

[Vedamurthy Joshi]

R2.20 Build 13 Ubuntu 14.04 Juno multinode setup

In this tor-scale setup, we have 128 TORs, 512 lifs on each tor, 2 vmis on each lif.
Each lif is part of different Vn (512 vns in all)

Totally,
128 tors
64K lifs
128K vmis
512 vns

nodei38 is the node which houses all these tor-agents

On ovs-vm1 (first ToR), an endpoint tried to do dhcp . The packet reaches the TSN, but no response is got

Praveen is aware of the issue

Support for >64K VMI and VRF

Few data structures in agent were using uint16_t to store VMI and VRF
index. Modified to use uint32_t
