v0.114.0

🛑 Breaking changes 🛑

• datadogexporter: Stop prefixing http_server_duration, http_server_request_size and http_server_response_size with otelcol (#36265)
  These metrics can be from SDKs rather than collector. Stop prefixing them to be consistent with https://opentelemetry.io/docs/collector/internal-telemetry/#lists-of-internal-metrics
• otelarrowreceiver: New admission control metrics are consistent across Arrow and OTLP data paths. (#36334)
  otelcol_otelarrow_admission_in_flight_bytes new, replaces otelcol_otel_arrow_receiver_in_flight_bytes
otelcol_otelarrow_admission_waiting_bytes: new, describes waiting requests
  otelcol_otel_arrow_receiver_in_flight_items: removed
  otelcol_otel_arrow_receiver_in_flight_requests: removed

🚩 Deprecations 🚩

• exporter/prometheusremotewrite: Deprecate configuration option export_created metric (#35003)
  Disable the exporter.prometheusremotewriteexporter.deprecateCreatedMetric feature gate to temporarily re-enable the created metric.

• googlemanagedprometheus: Add CumulativeNormalization config option to allow users to configure to specify whether to report normalized or un-normalized points. Defaults to normalized. (#36357)
• elasticsearchexporter: Translate k8s.*.name resource attributes in ECS mode (#36233)
  Translate k8s.job.name, k8s.cronjob.name, k8s.statefulset.name, k8s.replicaset.name, k8s.daemonset.name, k8s.container.name to kubernetes.*.name. Translate k8s.cluster.name to orchestrator.cluster.name.

• exporter/loadbalancing: Shutdown exporters during collector shutdown. This fixes a memory leak. (#36024)
• pkg/ottl: Respect the depth option when flattening slices using flatten (#36161)
