New component: Netflow/IPFIX receiver

[srclosson]

The purpose and use-cases of the new component

The new receiver would allow OTEL to collect netflow/IPFix data. Use cases cover

• Most ISP's
• Companies that need SIEM

Example configuration for the component

I'm wondering if it would make sense to do something equivalent to telegraph?

receivers:
  netflow:
     protocol: ipfix|netflow_v5|netflow_f9
     endpoint: 0.0.0.0:2055
     protocol: udp

Telemetry data types supported

Given the example from the telegraf input plugin, I would expect lots of metadata?

netflow,source=127.0.0.1,version=NetFlowV5 protocol="tcp",src="140.82.121.3",src_port=443u,dst="192.168.119.100",dst_port=55516u,flows=8u,in_bytes=87477u,in_packets=78u,first_switched=86400660u,last_switched=86403316u,tcp_flags="...PA...",engine_type="19",engine_id="0x56",sys_uptime=90003000u,src_tos="0x00",bgp_src_as=0u,bgp_dst_as=0u,src_mask=0u,dst_mask=0u,in_snmp=0u,out_snmp=0u,next_hop="0.0.0.0",seq_number=0u,sampling_interval=0u

The actual data would be heavily labelled. The preference would be to capture the data in the most usable and informative way possible. Given that this may result in high cardinality, it's suggested that the appropriate processor be used to translate metadata give the users unique use case.

Is this a vendor-specific component?
