Fix an issue when Octavia performs a failover of an ACTIVE-STANDBY load
balancer that has both amphorae missing.
Some tasks in the controller took too much time to timeout because the
timeout value defined in
``[haproxy_amphora].active_connection_max_retries`` and
``[haproxy_amphora].active_connection_rety_interval`` was not used.
