LU-11077 utils: move get/set/list_param into own file

Move the "lctl get_param/set_param/list_param" handling code into a
separate file so that the functions can be called within the code
elsewhere without the need for all the dependencies.

Remove obsolete "local_cfg" and "set_timeout" sub-commands that
have been obsolete since "set_param" was added.
