Routine to find out if DCNM is using http or https.

        DCNM 10 (Fuji-4) and above does not support http. Only https is
        supported and enabled by default.
        Prior DCNM versions supported both http and https. But, only http
        was enabled by default.
        So, enabler needs to find out if DCNM is supporting http or https to
        be friendly with the existing installed setups.
