Add BucketMetricValue interface (#24188) 

Unlike other implementations of InternalNumericMetricsAggregation.SingleValue,
the InternalBucketMetricValue aggregation currently doesn't implement a
specialized interface that exposes the `keys()` method. This change adds this so
that clients can access the keys via the interface.
