feat(runtime): remove public OTEL trace API (#26854)
This PR removes the public Deno.tracing.Span API. We are not confident we can ship an API that is better than the `@opentelemetry/api` API, because V8 CPED does not support us using `using` to manage span context. If this changes, we can revisit this decision. For now, users wanting custom spans can instrument their code using the `@opentelemetry/api` API and `@deno/otel`. This PR also speeds up the OTEL trace generation by a 30% by using Uint8Array instead of strings for the trace ID and span ID.

/**
|
||||
* **UNSTABLE**: New API, yet to be vetted.
|
||||
*
|
||||
* APIs for working with the OpenTelemetry observability framework. Deno can
|
||||
* export traces, metrics, and logs to OpenTelemetry compatible backends via
|
||||
* the OTLP protocol.
|
||||
*
|
||||
* Deno automatically instruments the runtime with OpenTelemetry traces and
|
||||
* metrics. This data is exported via OTLP to OpenTelemetry compatible
|
||||
* backends. User logs from the `console` API are exported as OpenTelemetry
|
||||
* logs via OTLP.
|
||||
*
|
||||
* User code can also create custom traces, metrics, and logs using the
|
||||
* OpenTelemetry API. This is done using the official OpenTelemetry package
|
||||
* for JavaScript:
|
||||
* [`npm:@opentelemetry/api`](https://opentelemetry.io/docs/languages/js/).
|
||||
* Deno integrates with this package to provide trace context propagation
|
||||
* between native Deno APIs (like `Deno.serve` or `fetch`) and custom user
|
||||
* code. Deno also provides APIs that allow exporting custom telemetry data
|
||||
* via the same OTLP channel used by the Deno runtime. This is done using the
|
||||
* [`jsr:@deno/otel`](https://jsr.io/@deno/otel) package.
|
||||
*
|
||||
* @example Using OpenTelemetry API to create custom traces
|
||||
* ```ts,ignore
|
||||
* import { trace } from "npm:@opentelemetry/api@1";
|
||||
* import "jsr:@deno/otel@0.0.2/register";
|
||||
*
|
||||
* const tracer = trace.getTracer("example-tracer");
|
||||
*
|
||||
* async function doWork() {
|
||||
* return tracer.startActiveSpan("doWork", async (span) => {
|
||||
* span.setAttribute("key", "value");
|
||||
* await new Promise((resolve) => setTimeout(resolve, 1000));
|
||||
* span.end();
|
||||
* });
|
||||
* }
|
||||
*
|
||||
* Deno.serve(async (req) => {
|
||||
* await doWork();
|
||||
* const resp = await fetch("https://example.com");
|
||||
* return resp;
|
