chore(config): Store default value in a box

[bruceg]

Another baby step towards making configuration schemas object safe. This stores the default value for the config metadata in a box instead of a concrete type. The type bounds on the metadata remain for now, as I'm trying to make this minimal behavior-preserving change before tackling the generic bounds. As far as I can tell from vector generate-schema, the resulting data is identical.

Regression Detector Results

Run ID: 8527b454-7911-4303-9b33-d3568a6e4f3a
Baseline: 6d43f48
Comparison: 9007e2f
Total vector CPUs: 7

Explanation

A regression 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.

The table below, if present, lists those experiments that have experienced a statistically significant change in mean optimization goal performance between baseline and comparison SHAs with 90.00% 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 ±5.00% change in their mean optimization goal are discarded. An experiment is erratic if its coefficient of variation is greater than 0.1. The abbreviated table will be omitted if no interesting change is observed.

No interesting changes in experiment optimization goals with confidence ≥ 90.00% and |Δ mean %| ≥ 5.00%.

Fine details of change detection per experiment.
