PSeitz 55b0b52457 Fix AggregationLimits (#2495 )

* change AggregationLimits behavior

This fixes an issue encountered with the current behaviour of
AggregationLimits.
Previously we had AggregationLimits and RessourceLimitGuard, which both
track the memory, but only RessourceLimitGuard released memory when
dropped, while AggregationLimits did not.

This PR changes AggregationLimits to be a guard itself and removes the
RessourceLimitGuard.

* rename AggregationLimits to AggregationLimitsGuard

Contributing

When adding new bucket aggregation make sure to extend the "test_aggregation_flushing" test for at least 2 levels.

Code Organization

Tantivy's aggregations have been designed to mimic the aggregations of elasticsearch.

The code is organized in submodules:

bucket

Contains all bucket aggregations, like range aggregation. These bucket aggregations group documents into buckets and can contain sub-aggregations.

metric

Contains all metric aggregations, like average aggregation. Metric aggregations do not have sub aggregations.

agg_req

agg_req contains the users aggregation request. Deserialization from json is compatible with elasticsearch aggregation requests.

agg_req_with_accessor

agg_req_with_accessor contains the users aggregation request enriched with fast field accessors etc, which are used during collection.

segment_agg_result

segment_agg_result contains the aggregation result tree, which is used for collection of a segment. The tree from agg_req_with_accessor is passed during collection.

intermediate_agg_result

intermediate_agg_result contains the aggregation tree for merging with other trees.

agg_result

agg_result contains the final aggregation tree.
