Title: add show filter to facilitate debugging

This is not a real filter , but more a tool to help you debug your conf.

When this filter if executed, it will show you through log, stdout/stderr, file a string you composed with the event data.

Helpful to show a string status before a f***ing grok filter that don't match as you expect.
