Implements #1072
Additional implementations:
- l7 statistics for networks
Additional fixes and improvements:
- local networks traffic statistics were saved twice
- 5min.lua was not properly coded to keep into account user
preferences
_ 5min.lua has been simplified
TODO:
- ooo / retransmissions / lost counters should be accounted in the C engine or
serialized to disk as idle hosts may determine a decrease in the
aforementioned counters.
Flows sent via nProbe (proxy mode) carry information on the exporter
address (EXPORTER_IPV4_ADDRESS) and on the exporter interfaces
(INPUT_SNMP and OUTPUT_SNMP). This implementation attempts at saving
this information to allow comparisons with raw SNMP data.
