* split block mine to mineBlockSize() from mineCapacity()

Browse source 
* 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'
