Remove AggregationStreams and friends

* Remove outdated aggregation registration method
* Remove AggregationStreams
* Adds StreamInput#readNamedWriteableList and
StreamOutput#writeNamedWriteableList convenience methods. We strive to
make the reading and writing from the streams terse so they are easier
to scan visually.
* Remove PipelineAggregatorStreams
* Remove stream info from InternalAggreation.Type
* Remove InternalAggregation#type
* Remove Streamable from PipelineAggregator
* Remove Streamable from MultiBucketsAggregation.Bucket
