Support output formats other than protobuf over Kafka

[sjwang90]

Background/Use Case

InfluxData's Telegraf project received a request (influxdata/telegraf#8425) to integrated into goFlow for IPFIX/NetFlow support. Currently Telegraf does not support binary (ex: protobuf) formats.

Feature Request

Request for vFlow to add one of the following output formats to ease the integration with Telegraf.

• InfluxDB Line Protocol
• Carbon2
• Graphite
• JSON
• Prometheus
• SplunkMetric
• Wavefront
• ServiceNow Metrics

Also not sure if goFlow is meant to be embedded in other programs as there might not be a stable library API for other programs use.

@sjwang90 thanks! I added a comment on the telegraf thread.
GoFlow can be extended but the main format in this repository is Kafka+protobuf (or JSON).
For Influx/Telegraf, you will likely need aggregation.

Ok thanks for your feedback @lspgn. I'll close this issue for now.
