LU-18715 utils: Extend lctl nodemap_info with property values

The command "lctl nodemap_info" only presents information about which
property names exist for a given nodemap. It does not show the values
for each property, and the command's usefulness is therefore limited.
Further, nodemap property values are generally retrieved via the "lctl
get_param" interface which is inconsistent with how nodemap properties
are set, i.e., by using the "lctl nodemap_*" interface rather than the
"lctl set_param" interface.

This patch extends the "lctl nodemap_info" command to improve
usability, presenting in-depth information, including the global
nodemap state (active/inactive), property availability and
descriptions, all defined nodemaps, and the values for all nodemap
properties.

Extended options:
lctl nodemap_info [-l/--list] [-n/--name NODEMAP_NAME]
[-p/--property PROPERTY_NAME]

List the values of all properties for all nodemaps:
"lctl nodemap_info"

List the value of the specific "ranges" property for the "remote"
nodemap: "lctl nodemap_info --name remote --property ranges"

"--name" and "--property" can be used individually to show the
properties of all nodemaps or all properties of a specific nodemap.
Note the previous positional arguments [all,list,<nodemap>] are
retained for backward-compatibility.

Added sanity-sec 25a to test these modifications.
