[SCSI] target: add initial statistics
This patch adds a target_core_mib.c statistics conversion for
backend context struct se_subsystem_dev + struct se_device config_group
based statistics in target_core_device.c using CONFIGFS_EATTR()
based struct config_item_types from target_core_stat.c code.
The conversion from backend /proc/scsi_target/mib/ context output to configfs
default groups+attributes include scsi_dev, scsi_lu, and scsi_tgt_dev output
from within individual:
/sys/kernel/config/target/core/$HBA/DEV/
The legacy procfs output now appear as individual configfs attributes under:
*) $HBA/$DEV/statistics/scsi_dev:
|-- indx
|-- inst
|-- ports
`-- role
*) $HBA/$DEV/statistics/scsi_lu:
|-- creation_time

The conversion from backend /proc/scsi_target/mib/ context output to configfs

Also, this includes adding struct target_fabric_configfs_template->
tfc_wwn_fabric_stats_cit and ->tfc_tpg_nacl_stat_cit respectively for
use during target_core_fabric_configfs.c:target_fabric_setup_cits()
