> Rather than having users configure explicit penalization periods and requiring developers to implement it in their processors we can automate this.  Perhaps keep a LinkedHashMap<Connection ID, Counter> of size 5 or so in the FlowFileRecord construct.  When a FlowFile is routed to a Connection, the counter is incremented.  If the counter exceeds 3 visits to the same connection, the FlowFile will be automatically penalized.  This protects us "5 hops out" so that if we have something like DistributeLoad -> PostHTTP with failure looping back to DistributeLoad, we will still penalize when appropriate.
> In addition, we will remove the configuration option from the UI, setting the penalization period to some default such as 5 seconds.
