Refactor netflow codec.

Netflow field definitions are now extracted to a bundled YAML file and also
introduces a new config directive to specify an additional YAML file that
can be used to augment the built-in list. This means adding new Netflow field
types doesn't require a rebuild of Logstash.

TODO Work out how to get the YAML file added to the jar.
