  - Test the deletion of chain
    
    This is the flow of the test:
    
    1 - Create a vnffg in tacker (i.e. chain + classifier)
    2 - Remove the vnffg
    3 - Check that the RSPs are removed from operation DB in ODL and
    the classifier rules are not present in the flows
    4 - Create a new vnffg
    5 - Test the new chain:
      5.1 - Check HTTP traffic works
      5.2 - Block HTTP traffic in VNF and check that it does not work anymore
