> 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.
