It looks like all files under internal/configconverter/dpfilters were copied from the SignalFx exporter to enable this config converter:

// Temporary copied from the SignalFx exporter to be used in DisableKubeletUtilizationMetrics converter.

I believe the whole directory can be removed, but it'd have to be tested to make sure there aren't other references.
