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

[~markap14] I will pick this up for review if you don't have the time, because I've been in the ControlRate code before.  Let me know.

> The {{ControlRate}} processor implements a {{FlowFileFilter}} that returns the {{FlowFileFilter.ACCEPT_AND_TERMINATE}} result if the {{FlowFile}} fits with the rate limit, affectively limiting it to one {{FlowFile}} per {{ConrolRate.onTrigger()}} invocation.  This is a significant bottleneck when processing very large quantities of small files making it unlikely to hit the rate limits.
> It should allow multiple files, perhaps with a configurable maximum, per {{ControlRate.onTrigger()}} invocation by issuing the {{FlowFileFilter.ACCEPT_AND_CONTINUE}} result until the limits are reached.  In a preliminary test this eliminated the bottleneck.
