* TODO: Support Putting vnf type = vpe and vce
*
* This class supports the GenericPutVnf Sub Flow.
* This Generic sub flow can be used by any flow for accomplishing
* the goal of Creating/Updating(PUT) a Vnf Object (in AAI). The flow
* supports the Creating/Updating of 3 types of Vnfs (generic-vnf, vce, and vpe).
* The "type" must be provided by the calling flow and this type should
* be mapped to the variable GENPV_type. The type should either be
* "generic-vnf", "vce", or "vpe". In addition, the Vnf Id and
* payload should be provided.
*
* Upon successful completion of this sub flow the
* GENPV_SuccessIndicator. An MSOWorkflowException will
* be thrown if an error occurs at any time during this
* sub flow. Please map input variables to the corresponding
* variable names below.
*
*
* Incoming Required Variables:
* @param - GENPV_vnfId
* @param - GENPV_vnfPayload
* @param - GENPV_type
*
*
* Outgoing Variables:
* @param - GENPV_SuccessIndicator
* @param - WorkflowException
