Before this commit, multiple L3 hosts were allocated if the same ip
address was seen with multiple mac addresses. We have decided to keep
ip and macs logically sepatated. For this reason, after this commit,
the L3 ip always remains the same even if there are changes in the
mac. A user who wants to monitor mac addresses can use the L2 section
as well as the host pools.
This commit also reverts:
"Add MAC address to the serialized hosts key to fix bad MAC address association and stats"
This reverts commit 89a756fb9a.
