Pull request overview
This PR adds optional client-side telemetry support for Datadog StatsD clients. The feature tracks metrics about the client itself (metrics sent, bytes transferred, packets dropped) to help diagnose high-throughput delivery issues. Telemetry is disabled by default and automatically excluded from mock/Telegraf modes.
Key Changes:
- New
Telemetryclass to track and periodically flush client metrics - Integration into the StatsD client with opt-in
includeDatadogTelemetryflag - Child clients inherit parent telemetry to consolidate tracking
