+    Added new heat param OVNOpenflowProbeInterval to set ovn_openflow_probe_interval
+    which is inactivity probe interval of the OpenFlow connection to the OpenvSwitch
+    integration bridge, in seconds. If the value is zero, it disables the connection
+    keepalive feature, by default this value is set on 60s.
+    If the value is nonzero, then it will be forced to a value of at least 5s.
