Upgraded to Elasticsearch 8.11.4.
Added the truncation trace in search requests executed with the adaptive query planner.

Fixed an issue that created a stage node for a cached join in the adaptive query planner.
Fixed an issue with the creation of function_score queries when the boost_mode parameter isn’t passed explicitly.

Fixed an incomplete response when doing an aggregation and no index could match the request due to a date range filter.
Fixed an issue on cache key definition when runtime fields were defined at query time.
Fixed an issue on a cached join when its parent was shared by two other parents.
Fixed an issue when computing the index scan cost, where the field existed but without terms in a segment.
Fixed a concurrency issue in multi-conditional index joins.
Fixed a concurrency issue in Point-In-Time query shard cache.
Fixed a concurrency issue in AQP reports.

Upgraded to Elasticsearch 8.11.1
Added a circuit-breaker mechanism that makes multi-conditional joins fail fast if the INDEX_JOIN strategy needs to perform many index lookups that require a long processing time.
- The maximum number of allowed lookups is controlled by a new dynamic setting (siren.planner.index_join.max_lookups).
- The default value for this setting is 20,000.
Updated the off-heap memory settings siren.memory.{root,job,task}.limit to be dynamic, facilitating the setup and configuration of Federate clusters.
Added cache capabilities for AQP requests.
Enabled Point-in-Time (PIT) for inner join requests.
Added the keep-alive parameter for PIT requests.
Introduced a resource manager for better handling of the resource life-cycle.
Improved documentation with a table of operator compatibility for every data type.
Improved documentation on joins with nested fields.

Deprecated the Ingestion API.
- All requests under /_siren/connector/ingestion are marked as deprecated.
- The following settings are also marked as deprecated:
  - siren.connector.ingestions.index, siren.connector.ingestion.bulk_size, siren.connector.ingestion.fetch_size, siren.connector.ingestion.index_timeout,
Deprecated the Job API.
- All requests under /_siren/connector/jobs are marked as deprecated.

Fixed an issue when the join query is not specified. A match_all query is used by default.
Fixed a query cache miss when changing the order of conditions in a multi-conditional join request.
