…er (open-telemetry#32327)

**Description:** <Describe what has changed.>
<!--Ex. Fixing a bug - Describe the bug and how this fixes the issue.
Ex. Adding a feature - Explain what this achieves.-->
This PR adds support for the logs agent exporter in order to export logs
to Datadog. The following changes were made in order to support this:
- Update datadog-agent modules to the following commit hash version:
DataDog/datadog-agent@a1ef7ed
- Remove `peer_service_aggregation` config option which was deprecated
and removed since last datadog-agent version:
DataDog/datadog-agent#23284
- Add logs agent exporter setup in datadog exporter factory. This is
disabled by default and can be enabled via feature gate.
