Liang-Chi Hsieh bdac19184a [SPARK-35230][SQL] Move custom metric classes to proper package ... ### What changes were proposed in this pull request? This patch moves DS v2 custom metric classes to `org.apache.spark.sql.connector.metric` package. Moving `CustomAvgMetric` and `CustomSumMetric` to above package and make them as public java abstract class too. ### Why are the changes needed? `CustomAvgMetric` and `CustomSumMetric` should be public APIs for developers to extend. As there are a few metric classes, we should put them together in one package. ### Does this PR introduce _any_ user-facing change? No, dev only and they are not released yet. ### How was this patch tested? Unit tests. Closes #32348 from viirya/move-custom-metric-classes.
