Describe the issue you're reporting

When using recent versions of the DogStatsD client (e.g. Java client) I noticed that metrics sent by the client weren't captured by the statsd receiver. The cause of this issue boils down to the statsd receiver rejecting metrics that contain unrecognized parts, and DogStatsD emits metrics with extra fields that are currently unsupported by the receiver.

In particular, there are 2 new fields that are currently unsupported by the receiver:

• Container ID (since DogStatsD v1.2)
• Timestamp (since DogStatsD v1.3)

Example of a metric that the statsd receiver drops due to the unrecognized parts:

workflow_execution.failure:1|c|#workflow.version:2,workflow.name:Telemetry 2|c:abc123"

PR to fix this: #31296

[dmitryax]

I'm wondering if this additional support should be configurable. But given that we already support tags that are part of the DogStatsD, I think supporting these additional parts OOTB is ok. Later, if we want to define the format in the configuration explicitly, we can have dogstatsd as a default option to keep the backward compatibility.

I believe this was completed by #31296, so I'm going to close. Let me know if I misunderstood.
