### What would you like to happen?
Dataflow service side is working on returning the BoundedTrie metrics.
Run into the following error:
```
java.lang.ClassCastException: com.google.api.client.util.ArrayMap cannot be
cast to org.apache.beam.model.pipeline.v1.MetricsApi$BoundedTrie

Changes needed here at
https://github.com/apache/beam/blob/master/runners/google-cloud-dataflow-java/src/main/java/org/apache/beam/runners/dataflow/DataflowMetrics.java#L212
to translate from the struct returned by Dataflow into the BoundedTrie proto.
