Currently in https://github.com/elastic/apm-agent-python/blob/master/elasticapm/instrumentation/packages/elasticsearch.py#L47 we are discarding everything but the query in the body which can cover some very important (from a performance point of view) aspects of the operation for example pagination - large from/size can have severe impact - and aggregations - if present can severely impact everything.

It would also be great to track the statistics on the response:

took, hits.total, _shards.total/failed/successful information

which can expose badly structured code/queries or performance issues in elasticsearch

Thank you!
