LU-9680 obdclass: user netlink to collect devices information
Our utilities can report to users a device list with various bits
of data using the debugfs file 'devices'. This debugfs file is
only by default available to root which prevents regular users
from collecting information. Enable non-root users to collect
the same information for lctl dl using netlink. The advantage of
using netlink is that it also removes the 8K ioctl limit. Add the
ability to present this data in YAML format as well.
