This field is a map of field paths to dimension names. It defines the dimensions to associate with this metric in
CloudWatch The value of this field is used only if the metric destination is <code>CloudWatch</code>. If the
metric destination is <code>Evidently</code>, the value of <code>DimensionKeys</code> is ignored.
