Previously neutron was keeping track of dhcp lease time in order to ensure it didn't hand out an ip address that was already leased. This patch removes that logic and instead leverages the dhcp_release utility. This allows us to reuse ip addresses immediately after a port is deleted. This patch also bumps the lease time to 24 hours instead of 2 minutes with reduces the amount of dhcp traffic. DocImpact There is a DocImpact for this bug related to the upgrade path. One should first upgrade their dhcp-agents. Then wait till the dhcp_lease time has expired. Lastly, update neutron-server in order to avoid the case where an instance is deleted and the dnsmasq process has not released the lease and neturon allocates that ip to a new port. Fixes bug: 1202392 Implements blueprint: remove-dhcp-lease Change-Id: Ifcb4f093c92904ceb896438987d53e692eb7fb26
