    VNF Indicator interface of ETSI NFV SOL002.
    
    This API allows the EM/VNF to provide information on value changes of VNF related indicators. 
    VNF related indicators are declared in the VNFD.

              it shall be supported by the VNFM in the filter expression. If receiving, this parameter is not
              supported a 400 Bad Request response shall be returned (See table 8.4.2.3.2-2).
