-----------------------------------

             Summary: Allow MessageParsers to be have configs be updateable
                 Key: METRON-1753
                 URL: https://issues.apache.org/jira/browse/METRON-1753
             Project: Metron
          Issue Type: Improvement
            Reporter: Justin Leet


This came up in a review https://github.com/apache/metron/pull/1175#discussion_r212985523

ParserBolt doesn't implement the `reloadCallback` that the enrichment bolts do. This means they can't update on config changes the same way.

I expect adding this capability is something to the effect of:
* Add update method to MessageParser
* Implement reloadCallback to update the parser configs and make sure anything else in the bolt gets updated as necessary.
* Tests and docs
* Update any parsers that use configs to handle this appropriately.
