Subject: [PATCH] - keep a topology map in elasticsearch with all public IPs
 that each agent has - at startup, each agent adds its IPs to the topology map
 (in elasticsearch under packetbeat-topology index) - determine src_server and
 dst_server for each transaction - ignore duplicated transactions
