Issue:
Remove dependency on jaeger-lib
There are several issues with the dependency on jaeger-lib:
  * it is shared with jaeger-client-go, which is now deprecated, so the library does not need to be standalone
  * library does not use go modules, migrating it to `go mod` is non-trivial because it's already v2
  * because it cannot be migrated to go modules, it cannot be upgraded to later versions of go-kit. The older 0.11 version of go-kit has dependencies with known vulnerabilities
  * there's not much need to depend on go-kit in the first place, we're only using it for its expvar package, which is relatively trivial to implement (especially without the histograms)

There are two directions we can take:
  1. migrate to OpenTelemetry instead. This is preferable, but will involve non-trivial amount of work. Good news is that work can likely be done piecemeal.
  2. Keep using jaeger-lib API for metrics and pull it inside this repo as `internal`.
    * unfortunately, this does not fully remove dependency on jaeger-lib because we're still using jaeger-client-go (cf. #3381, #3380)
  3. Keep using jaeger-lib API for metrics but implement it with OpenTelemetry SDK. This seems like the least resistance path (need to prototype it to test viability).

(Update 2023-01-29) Current plan:
  * [x] Clone jaeger-lib into Jaeger repo (done in #3767, #3772)
  * [x] Upgrade HotROD to use OTEL SDK (via OT bridge), which removes the need for uber/jaeger-lib (done in #4187)
  * [x] Upgrade tracegen to use OTEL SDK (done in #4189)
  * [x] Upgrade collector/query/all-in-one to use OTEL SDK (via OT bridge)
  * [x] Fix crossdock (maybe we don't need SDK testing there anymore)

+# Crossdock End-to-End Tests
+
+This document describes the end-to-end (E2E) testing infrastructure implemented in the `ci-crossdock.yml` GitHub Actions workflow.
+
+## Overview
+
+The Crossdock tests are E2E integration tests that verify Jaeger's ability to receive traces from various client libraries and encoding formats. The tests use the [Crossdock](https://github.com/crossdock/crossdock) framework to orchestrate multi-container test scenarios.
+
+## Architecture
+
+The test environment consists of the following components:

+
+### Components
+
+1. **Crossdock Orchestrator** (`crossdock/crossdock`): The test framework that coordinates test execution across multiple containers.
+
+2. **Test Driver** (`jaegertracing/test-driver`): A custom Go application (built from `/crossdock/main.go`) that:
+   - Waits for Jaeger components to be healthy
+   - Instructs client services to create traces
+   - Queries Jaeger Query API to verify traces were stored correctly
+
+3. **Zipkin-Brave Clients** (`jaegertracing/xdock-zipkin-brave`): Java-based trace generators using the Zipkin Brave library. Multiple instances test different encoding formats:
+   - `zipkin-brave-thrift`: Thrift encoding
+   - `zipkin-brave-json`: JSON encoding (v1)
+   - `zipkin-brave-json-v2`: JSON encoding (v2)
+   - `zipkin-brave-proto`: Protobuf encoding
+
+4. **Jaeger Backend**: Full Jaeger deployment including:
+   - `jaeger-collector`: Receives spans via Zipkin-compatible endpoint (port 9411)
+   - `jaeger-query`: Provides API for trace retrieval
+   - `jaeger-remote-storage`: In-memory storage backend
+
+## Test Flow
+
+1. **Setup Phase**:
+   - Docker Compose starts all containers
+   - Test Driver waits for Jaeger Query and Collector health checks
+
+2. **Test Execution** (EndToEnd behavior):
+   - Crossdock orchestrator calls Test Driver with a service parameter
+   - Test Driver sends HTTP POST to the specified client service (e.g., `zipkin-brave-thrift:8081/create_traces`)
+   - Client service creates traces with unique random tags and sends them to Jaeger Collector
+   - Test Driver queries Jaeger Query API to retrieve traces matching the tags
+   - Test validates that expected traces were received and stored correctly
+
+3. **Validation**:
+   - Verifies correct number of traces received
+   - Validates that all expected tags are present in stored spans

+# Build and run crossdock tests
+make build-and-run-crossdock
+
+# View logs on failure
+make crossdock-logs
+
+# Clean up containers
+make crossdock-clean
+```
+
+## GitHub Actions Workflow
+
+The `ci-crossdock.yml` workflow:
+1. Triggers on pushes to `main`, pull requests, and merge queue
+2. Builds all required Docker images (Jaeger binaries + test driver)
+3. Runs the crossdock test suite via `scripts/build/build-crossdock.sh`
+4. On success for `main` branch: publishes test-driver image to Docker Hub and Quay.io
+5. On failure: outputs container logs for debugging
+
+## Test Behaviors
+
+| Behavior | Description |
+|----------|-------------|
+| `endtoend` | Creates traces via client services and verifies they are queryable in Jaeger |
+| `adaptive` | (Legacy) Tests adaptive sampling rate calculation and propagation |
+
+## Environment Variables
+
+| Variable | Description |
+|----------|-------------|
+| `JAEGER_COLLECTOR_HOST_PORT` | Collector endpoint for clients |
+| `JAEGER_COLLECTOR_HC_HOST_PORT` | Collector health check endpoint |
+| `JAEGER_QUERY_HOST_PORT` | Query API endpoint |
+| `JAEGER_QUERY_HC_HOST_PORT` | Query health check endpoint |
