Add OTLP trace export tests + Rust weblog [rust@brian.marks/otlp-trace-export][ruby@brian.marks/otlp-trace-export][php@brian.marks/otlp-trace-export]

[bm1549]

Motivation

Cross-language OTLP Traces Export effort (RFC "OTLP Traces Export 2026Q1", Phase 1). The existing Test_Otel_Tracing_OTLP (scenario apm_tracing_otlp) was active for python/nodejs/golang/java/dotnet and missing_feature for rust/ruby/php. This PR activates it for rust, ruby, and php, and adds the Rust end-to-end weblog that was missing.

Changes

• New Rust axum e2e weblog under utils/build/docker/rust/weblog/ (+ axum.Dockerfile): GET /, GET /make_distant_call?url=, GET /healthcheck, instrumented with dd-trace-rs from the brian.marks/otlp-trace-export branch (trace-only features). The server span sets http.request.headers.user-agent so get_otel_spans correlates the exported span to the request.
• Activate Test_Otel_Tracing_OTLP in manifests/{rust,ruby,php}.yml (missing_feature → v0.3.4-dev / v2.36.0-dev / v1.21.0-dev). No test logic changed; no language carve-outs.
• docs/execute/build.md: list rust and its axum weblog.

Ruby (rails72) and PHP (apache-mod-8.0) weblogs already implement the required endpoints — no weblog changes there.

Workflow

1. ⚠️ Created as draft.
2. The [lang@branch] title annotations point CI at the tracer feature branches; they will be removed before merge once the tracer PRs land.
3. Test logic is not modified (only a new weblog + manifests + docs).

Depends on the tracer PRs below being available (CI clones dd-trace-rs via rust-load-from-git). See Related PRs.

Reviewer checklist

• Anything but tests/ or manifests/ is modified? — yes (new Rust weblog + docs); R&P review may be needed.
• A docker base image is modified? — a new Rust weblog image is added.
• A scenario is added/removed/renamed? — no (reuses apm_tracing_otlp).

• libdatadog (sidecar OTLP path — merge-order gate for dd-trace-php): feat(sidecar): export session traces over OTLP via TraceExporter libdatadog#2101
• system-tests (e2e tests + Rust weblog): Add OTLP trace export tests + Rust weblog [rust@brian.marks/otlp-trace-export][ruby@brian.marks/otlp-trace-export][php@brian.marks/otlp-trace-export] #7121

Merge order: libdatadog #2101 → dd-trace-php #3971 (re-bump the submodule to the released libdatadog commit). system-tests #7121 validates rust/ruby/php once the tracer branches are available.
