[ https://git-wip-us.apache.org/repos/asf?p=nifi.git;h=ef69fd6 ]
NIFI-3479: This closes #1511. Updated StandardProvenanceEventRecord to
incorporate 'childFlowFiles' and 'parentFlowFiles' in the hashCode() method.
This allows many CLONE provenance Events to be added to the same Hash Set
without them all colliding
> NiFi is very inefficient when cloning a relationship if many Provenance
> Events are generated

> If I feed in a text file that has 10,000 lines to a SplitText Processor, the
> Processor will handle the file very quickly. However, if I then clone the
> 'splits' relationship to a second destination, the processor suddenly takes
> 18 seconds to process that same FlowFile.
