Dimitris Athanasiou 72f7698647 [ML] Extend aggregation support (elastic/x-pack-elasticsearch#705)
* [ML] Allow summary_count_field_name to be set to custom field

... in aggregated datafeeds.

This allows implementing e.g. distinct_count anomaly detection
with aggregations. (see case 1 in elastic/x-pack-elasticsearch#659)

Relates to elastic/x-pack-elasticsearch#659

* [ML] Handle multiple leaf aggregations

This commit allows multiple numeric leaf aggregations.
That enables use cases where the data are presummarised and
thus the summary count field is a sum aggregation on the
event rate field. (see 2 in elastic/x-pack-elasticsearch#659)
