[LUDOC-364] Update description of "lctl get_param nis" in Lustre manual

Description

The output from the command lctl get_param nis in current versions of Lustre does not match the description in the Lustre manual. New fields have been added to the ouput that have not been documented.

The manual currently has the following example output with a tabel afterwards describing each column:

# lctl get_param nis
nid                    refs   peer    max   tx    min
0@lo                   3      0       0     0     0
192.168.10.34@tcp      4      8       256   256   252

By contrast, Lustre version 2.7 has the following output:

[root@ct7-mds2 ~]# lctl get_param nis
nis=nid                      status alive refs peer  rtr   max    tx   min
0@lo                         up     0    3    0    0     0     0     0
192.168.2.12@tcp             up    -1    4    8    0   256   256   251

The columns status, alive and rtr are not documented.

FWIW, there also seems to be an entry per CPT, but there is no column showing which CPT the line is for.
