Enhancements to flow trace options

Flow trace granularity has been enhanced to filter logs effectively. As a result you can access relevant trace messages easily and avoid large traces that slow down your system. You can set the level of message you want displayed by using the new trace-level statement at the [edit security flow traceoptions] hierarchy level. You can use new flags to trace additional operations such as fragmentation, high availability, multicast, session, tunnel, and route.
