cpu_utill metric will be remowed. Need to rewrite template using cpu metric and boost timers to 20 minutes

[Alexander Nagovitsyn (gluk12189)]

CREATE failed: Forbidden: resources.cpu_alarm_low error associated with cpu_utill metric in template - when we have >1 agent this metric can be used to agent with empty cache. But the old metric is in another agent
