+1 via inspection. This is a great contribution. Thanks, Simon. I think
it would be nice to get more test data from different instances of Arcsight.
Does anyone in the community have access to this data set? This is the
official CEF spec.

Would be nice to find a test set that covers most of this.
> Create CEF Parser
> -----------------
>
> Key: METRON-157
> URL: https://issues.apache.org/jira/browse/METRON-157
> Project: Metron
> Issue Type: New Feature
> Reporter: Domenic Puzio
> Priority: Minor
> Labels: platform
>
> Create a parser for CEF (Common Event Format). CEF is a very common
> formatting for security data sources; it is used by FireEye, Adallom, Imperva
> WAF, CyberArk, and others. The parser should be flexible enough to work for
> any of these data sources. CEF uses shorthand field names, so field names
> should be changed to human-readable and Metron-friendly equivalents. CEF
> custom labels (cs1Label, flexString1Label, etc.) should be converted
> appropriately.
> Below are sample messages and their expected parsed output.
