A new configuration option, ``cleanup_on_shutdown``, was added to the
L3 agent. If set to True the L3 agent will explicitly delete all routers
on shutdown. For L3 HA routers it includes a graceful shutdown of
keepalived and the state change monitor, which will allow a faster failover
in certain conditions. The default value of ``cleanup_on_shutdown`` is
False to maintain backward compatibility. Setting to True could affect
the data plane when stopping or restarting the L3 agent.
