Test harness

[djeebus]

simple script to generate times for resuming and pausing sandboxes

---

Note

Adds a Go benchmark to start/pause/resume sandboxes (with optional OTel tracing) and declares the otlptracegrpc exporter as a direct dependency.

• Tests/Benchmark:
  • Add packages/orchestrator/benchmark_test.go implementing a benchmark to start, pause, resume, and close sandboxes using sandbox.Factory and template.Cache.
  • Builds template on first run if missing, downloads kernel if absent, sets up network/NBD pools, proxy, and builder.
  • Supports test cycles (only-start, start-and-pause, start-pause-resume) and optional OTel tracing via OTEL_EXPORTER_OTLP_ENDPOINT.
• Telemetry:
  • Initialize tracer provider using go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc when endpoint is set.
• Dependencies:
  • Promote go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc v1.38.0 to a direct dependency in go.mod.
