Enhanced system logging daemon (add-contextual-data plugin)

syslog-ng is an enhanced log daemon, supporting a wide range of input and output methods: syslog, unstructured text, message queues, databases (SQL and NoSQL alike) and more.

Key features:

 * receive and send RFC3164 and RFC5424 style syslog messages
 * work with any kind of unstructured data
 * receive and send JSON formatted messages
 * classify and structure logs with builtin parsers (csv-parser(),
   db-parser(), etc.)
 * normalize, crunch and process logs as they flow through the system
 * hand on messages for further processing using message queues (like
   AMQP), files or databases (like PostgreSQL or MongoDB).

This package provides the add-contextual-data module for syslog-ng. With this module syslog-ng can use an external database file to append custom name-value pairs on incoming logs (to enrich messages). The database is a file that containing `<selector, name, value>` records. Currently only `CSV` format is supported. It is like `geoip parser` where the selector is `$HOST`, but the user can define the selector, and also the database contents.
