* 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 \
--tolerance=verypermissive --nocheck=standby --format=brief --log=error \
/dev/nvme11 --json | jq '.nvme_total_capacity'

Prometheus naming conventions reserve `_count` for the counter in
histograms. For gauge values the naming convention is to use the plural
of the thing being counted.

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`
