HDD Vender detection for NuObjectV2

[yamingk]

As of the creation of this issue, the HDD in our env is BD2G7.
Need to make according change after tess team are able to export env value for new HDD vendor for SDS team to consume, or work out another way to better flexiable for future extentions of new HDD venders if they were to be supported by NuObjectV2.

static std::string get_raid_hdd_vendor_model() {
...
    char* mdl = std::getenv("PRODUCTION_ID_data1");  // <<<<<<<<<<<<<<<<<<<<<<<<
    LOGMSG_ASSERT(mdl, "vendor model is empty - check $PRODUCTION_ID_data1");
...
}
