metric sorting and grouping in Summary node
Refactor PlotName -> MetricName
Refactor MetricNameDto
Refactor MetricNameDto=PlotNameDto
Refactor PlotNameDto deleted
Refactor prepare PlotNode to extend MetricNode
Refactor PlotNode extends MetricNode
TestDetailsNode now extends MetricGroupNode => same behavior like Summary (grouping according to rules)
Both Summary and Metrics nodes in control tree are implemented with same classes and grouped in the same way
Code clean and resolve problems with commas in standard metric ids
