-- `metricName` - Name to identify the Metric in the external.metrics.k8s.io API. If using more than one trigger it is required that all `metricName`(s) be unique.
-- `query` - Predict query that will yield the value for the scaler to compare the `threshold` against. Query must return a vector/scalar single element response
-- `queryStep` - The maximum time between two slices within the boundaries for QML range query, used in query.
