[PATCH blktests V2 1/3] nvme: allow target to set cntlid min/max & model

[Chaitanya Kulkarni <chaitanya.kulkarni@wdc.com>]

This patch updates helper function create_nvmet_subsystem() to handle
newly introduced model, cntlid_min and cntlid_max attributes.
Also, this adds SKIP reason when attributes are not found in the
configfs.
