Sanitizing the metric names can lead to duplicate metric names: ``` caller=level.go:63 level=error caller="error gathering metrics: [from Gatherer #2] collected metric \"node_ethtool_giant_hdr\" { label:<name:\"device\" value:\"ens192\" > untyped:<value:0" msg=" > } was collected before with the same name and label values" ``` Generate a map from the sanitized metric names to the metric names from ethtool. In case of duplicate sanitized metric names drop both metrics, because it is unknown which one to take.
