      Description

      There are weird values of iowait metric on CPU usage charts for MariaDB instance.
      Summary dashboards, Trends dashboard System dashboards and PMMdemo dashboards are affected.

      As I understand there are 2 problems:

      1. Wrong value of iowait metric
      2. Chart doesn't show correctly metrics if metrics have values more than 100%
