    NIFI-4528 The ref attribute in the request to view content sent by th…

    …e client will now be inspected for the proxy context path. If found, it 
will be removed so the request can be successfully made within the cluster.
    
    To test this PR:
    Start a NiFi cluster
    Start a proxy that points to one of the nodes in the NiFi cluster
    From the NiFi UI, create a flow with a GenerateFlowFile processor creating 
text flowfiles sent to a downstream processor.  No need to start the downstream 
processor.
    List the queue contents
    Click the info icon of a flowfile in the queue
    Click View
    
    You should successfully see the content of the flowfile in the Content 
Viewer UI.

> that attribute is used to make the request within the cluster, and fails.
