    Fixes vnf create failure even if all parameters are supplied

    This commit adds code to fix the issue where vnf creation fails even
    if all the parameter values are supplied for the get_input parameters
    in VNFD template. The code was not properly handling the scenario
    where a certain non-vdu section may not have been parameterized in the
    VNFD template
