LU-16134 utils: adds lctl apply_yaml

Commnad set_param -F is used to parse yaml file with settings,
and makes set_param -P for it. Many type of settings are based
on a specific device and have conf_param type. When such settings
goes to set_param -P, all nodes tries to apply it and many errors
happen.
systemd-udevd[568906]: Process '/usr/sbin/lctl set_param
'osp.kjcf04-OST0003-osc-MDT0000.resend_count=43''
failed with exit code 2.

The patch adds functionality for conf_param event of YAML file,
and introduces lctl apply_yaml for both types of event.
YAML example
- {device: testfs-MDT0001, event: conf_param, index: 76, parameter:
   lod.qos_threshold_rr=100}
- { index: 17, event: set_param, device: general,
    parameter: jobid_var, value: procname_uid }
