with empty GZIP HTTP response
URL: https://github.com/apache/nifi/pull/4127
 
 
   Thank you for submitting a contribution to Apache NiFi.
   
   Please provide a short description of the PR here:
   
   #### Description of PR
   
   The initial issue is that when the server's response is indicating 
**Content-Encoding** as **GZIP** but with no content, we hit an EOF Exception 
(see [NIFI-4970](https://issues.apache.org/jira/browse/NIFI-4970)). The [first 
PR #4109](https://github.com/apache/nifi/pull/4109) added a unit test to 
reproduce the issue and a potential way of dealing with the issue by checking 
``responseBody.contentLength() > 0``. The problem is that 
``responseBody.contentLength()`` will always be equal to ``-1`` when the server 
returns a GZIP (with or without actual content) and we're going to ignore the 
response in case there is content to process. This PR reverts the check but 
adds a property to let the user decides wether content is expected or not. In 
case it is expected to have no content from the server, this will be ignored 
and no exception will be generated.
