[LU-12841] Add ability for lctl get_param to get subfield of YAML output

Related — Tue, 13 Apr 2021 14:10:50 +0000

It would be useful to allow "lctl get_param" to extract a subfield from a YAML-formatted output, such as "osc.*.import:max_brw_size" instead of having to use awk. I think "lctl get_param <param>:<key>" would work to print only the associated value for "<key>". There are not currently any parameters that contain a ':'.
