Fix the following metrics that were exported as zero because the
exporter did not know how to read them for SCSI devices:
- smartctl_device_bytes_read
- smartctl_device_bytes_written
- smartctl_device_power_cycle_count
New metrics:
- smartctl_read_errors_corrected_by_eccdelayed
- smartctl_read_errors_corrected_by_eccfast
- smartctl_write_errors_corrected_by_eccdelayed
- smartctl_write_errors_corrected_by_eccfast
Fix labels:
- smartctl_device{model_name} is now populated for SCSI/SAS, using
scsi_model_name.
New labels:
- smartctl_device{} gains:
scsi_product,scsi_revision,scsi_vendor,scsi_version

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)

* remove redundant meta labels from SCSI metrics
* added `smartctl_device_nvme_capacity_bytes` metric
* for some devices, such as 2.5" NVMe Intel & Micron the `family` field may be empty
The `.user_capacity` exists only when NVMe have single namespace. Otherwise,
for NVMe deivces with multiple namespaces, when device name used witout
namespace number (exporter case) `.user_capacity` will be absent
```
smartctl --info --health --attributes \
--tolerance=verypermissive --nocheck=standby --format=brief --log=error \
/dev/nvme11 --json | jq '.user_capacity'
null
smartctl --info --health --attributes \

This value is reported in thousands (i.e., a value of 1 corresponds to 1000 units of 512 bytes written) and is rounded up.
When the LBA size is a value other than 512 bytes, the controller shall convert the amount of data written to 512 byte units.
Current code is using 1024 instead of 1000.

The requirement from field engineers is knowledge of the form factor of the device, i.e. 3.5", 2.5"
* updated EXAMPLE.md
* fixed copy-paste issue `Starting systemd_exporter`

Switch exporter over to standard Prometheus exporter flags and logging.
This eliminates the need for a configuraion file.
