enhancement(statsd sink): Adhere to instrumentation spec

[neuronull]

Closes: #14214

Epic: #13995

This is the sink that made me realize the EventsDropped aren't being handled by the sink retry code.
There is ongoing discussion on how to handle it but this PR bring statsd sink up to the current standards.

Soak Test Results

Explanation

A soak test is an integrated performance test for vector in a repeatable rig, with varying configuration for vector. What follows is a statistical summary of a brief vector run for each configuration across SHAs given above. The goal of these tests are to determine, quickly, if vector performance is changed and to what degree by a pull request. Where appropriate units are scaled per-core.

The table below, if present, lists those experiments that have experienced a statistically significant change in their throughput performance between baseline and comparision SHAs, with 90.0% confidence OR have been detected as newly erratic. Negative values mean that baseline is faster, positive comparison. Results that do not exhibit more than a ±8.87% change in mean throughput are discarded. An experiment is erratic if its coefficient of variation is greater than 0.3. The abbreviated table will be omitted if no interesting changes are observed.

No interesting changes in throughput with confidence ≥ 90.00% and absolute Δ mean >= ±8.87%:
