aojeagarcia c5a1214ca6 protect DHCP agent cache out of sync
If DHCP agent port cache is out of sync with neutron server, dnsmasq
entries are wrong and VMs may not acquire an IP because of duplicate
entries.

When DHCP agent executes port_create_end method, port's
IP should be checked before being used, if there are duplicate IP
addresses in the same network in the cache we should resync.
