chore(origindetection): implement LocalData struct for DogStatsD

[wdhif]

What does this PR do?

Implements the LocalData structure for DogStatsD.

Motivation

This is done to allow to switch from taggertypes to origindetection modules.

Describe how you validated your changes

QA is done by both unit tests and E2E tests.

Possible Drawbacks / Trade-offs

For now we are still relying on the current OriginInfo.ContainerID variable. Once every resolution methods (Inode and UDS) has been moved to the origindetection module, we will be able to remove those variables and fully switch to origindetection.Origininfo.

Explanation

Confidence level: 90.00%
Effect size tolerance: |Δ mean %| ≥ 5.00%

Performance changes are noted in the perf column of each table:

• ✅ = significantly better comparison variant performance
• ❌ = significantly worse comparison variant performance
• ➖ = no significant change in performance

A regression test is an A/B test of target performance in a repeatable rig, where "performance" is measured as "comparison variant minus baseline variant" for an optimization goal (e.g., ingress throughput). Due to intrinsic variability in measuring that goal, we can only estimate its mean value for each experiment; we report uncertainty in that value as a 90.00% confidence interval denoted "Δ mean % CI".

For each experiment, we decide whether a change in performance is a "regression" -- a change worth investigating further -- if all of the following criteria are true:

1. Its estimated |Δ mean %| ≥ 5.00%, indicating the change is big enough to merit a closer look.

2. Its 90.00% confidence interval "Δ mean % CI" does not contain zero, indicating that if our statistical model is accurate, there is at least a 90.00% chance there is a difference in performance between baseline and comparison variants.

3. Its configuration does not mark it "erratic".
