   # Summary
   The test 
`org.apache.nifi.remote.client.http.TestHttpClient#testSendSuccessWithProxy` is 
flaky. The reason for that is due to the non-deterministic behavior of 
`java.util.HashMap`, which makes no guarantees as to the order of the map.
   
   The fix is mainly to preserve the ordering when interact with the map object.
    
   # Brief changelog
   Change the usage of `java.util.HashMap` to `java.util.LinkedHashMap`. 
   
   LinkedHashMap in Java 8 is implemented using double-linked list, the list 
will define the iteration ordering, therefore, when interact with the map 
object, the order will be the same for different iteration of the test. 
   
   Due to this change, I also update the expected value used in the test.
