Add a Grok option

[JoaquinSV]

Hi, it is possible to add a grok parser in addition to the regex one?.
Regards,

Sounds nice to have it!

built-in filter_parser and fluent-plugin-grok-parser can handle Grok pattern.

For example (pseudo code):

<source>
  @type forward
  @label @rewritetag
</source>

<label @rewritetag>
  <filter>
    @type parser
    <parse>
      @type grok
      <grok>
         pattern ...
      </grok>
    </parse>
  </filter>
  <match>
    @type rewrite_tag_filter
    <rule>
     ...
    </rule>
  </match>
</label>
