The Redact processor uses the Grok rules engine to
redact text in the input document that matches the
Grok pattern. For example Email or IP addresses can
be redacted using the definitions from the standard
Grok pattern bank. New patterns can be defined in
the processor configuration
The ingest attachment processor is currently available as a plugin. This
commit moves the processor to the default distribution so it is always
available.
