fix: Remove confused metrics
The exporter presently has metrics that are nonsense for a given type of drive, and remain at zero due to their defaults. Change the behavior to NOT emit a metric if the underlying JSON field is not present. Future related work may include parsing the corresponding metrics for SATA/SAS SSDs (e.g. `smartctl_device_percentage_used` could derived from `SSD_Life_Left` on some drives). Metrics no longer exported for the wrong type of drive: - `smartctl_device_nvme_capacity_bytes` (NVME-specific) - `smartctl_device_available_spare` (NVME-specific, ATA possible) - `smartctl_device_available_spare_threshold` (NVME-specific, ATA possible) - `smartctl_device_critical_warning` (NVME-specific, ATA possible) - `smartctl_device_interface_speed` (ATA-specific) - `smartctl_device_media_errors` (NVME-specific, ATA possible) - `smartctl_device_num_err_log_entries` (NVME-specific, SCSI uses distinct metrics, ATA possible) - `smartctl_device_nvme_capacity_bytes` (NVME-specific) - `smartctl_device_percentage_used` (NVME-specific, ATA possible) Signed-off-by: Robin H.
