Nik Everett 126619ae3c Add list of defered aggregations to the profiler (backport of #56208) (#56682) ... This adds a few things to the `breakdown` of the profiler: * `histogram` aggregations now contain `total_buckets` which is the count of buckets that they collected. This could be useful when debugging a histogram inside of another bucketing agg that is fairly selective. * All bucketing aggs that can delay their sub-aggregations will now add a list of delayed sub-aggregations. This is useful because we sometimes have fairly involved logic around which sub-aggregations get delayed and this will save you from having to guess. * Aggregtations wrapped in the `MultiBucketAggregatorWrapper` can't accurately add anything to the breakdown. Instead they the wrapper adds a marker entry `"multi_bucket_aggregator_wrapper": true` so we can be quickly pick out such aggregations when debugging. It also fixes a bug where `_count` breakdown entries were contributing to the overall `time_in_nanos`. They didn't add a large amount of time so it is unlikely that this caused a big problem, but I was there. To support the arbitrary breakdown data this reworks the profiler so that the `breakdown` can contain any data that is supported by `StreamOutput#writeGenericValue(Object)` and `XContentBuilder#value(Object)`.		2020-05-13 16:33:22 -04:00
