  - Merge "Modify instance resource list creation"
  - Modify instance resource list creation

    Modify instance resource list creation to avoid hard locking of
    model name in UUI request.

    e.g.
    VF resource and gruop resource has resource input
    vf { resource_input : { key1:value2, key2:[vf_prop_list,INDEX,key]|default}

    Derive the key ("vf_prop_list") from resource input and use this
    info to map UUI request.

    UUI req:
    {
    ...
      resourceInput: {
              vf_prop_list :   /// mapped with resource input of resource
                      {
    ....
