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

I would like to assign myself to this one. Have a pretty good idea on how I would implement it.

> Processor takes a FlowFile. It will then look for a retry attribute on the FlowFile. If none is present or if the designated retry attribute is set and not a number, the retry attribute is set to "1" and passed to a retry relationship.
> A configurable PropertyDescriptor contains the maximum number of times the FlowFile can be retried before being passed to a separate retries exceeded relationship. This PropertyDescriptor should have a validator for allowable positive integers for the retry.
> Processor may also conditionally penalize the FlowFile on the retry relationship.
>  
> Many interactions with NiFi request some information from a service and retry if the response isn't explicitly success. While it's quite common to use UpdateAttribute followed by a RouteOnAttribute to do this, there could be value in having a discreet processor for this.
