RELEASE_IP sometimes times out because killing TCP connections can
take a long time.
The aim of the takeover timeout is actually to limit the total amount
of time for an IP takeover run. So, calculate a combined timeout
offset once and use it for each of the RELEASE_IP, TAKEOVER_IP,
IPREALLOCATED stages. This gives RELEASE_IP more time to kill TCP
connections but still limits the total time.
