Add support for OTEL tracing
`crictl` now features 3 new CLI parameters: - `--enable-tracing`: Enable OpenTelemetry tracing. (default: false) - `--tracing-endpoint`: Address to which the gRPC tracing collector will send spans to. (default: "0.0.0.0:4317") - `--tracing-sampling-rate-per-million`: Number of samples to collect per million OpenTelemetry spans. Set to 1000000 or -1 to always sample. (default: -1) The tracer provider will be created on startup and the `Shutdown()` invocation will ensure that all spans are processed before exiting the binary. The `hack/tracing` directory contains scripts for local testing: ``` > ./hack/tracing/start … Everything is ready, open http://localhost:16686 to access jaeger ``` When now running `crictl` with `--enable-tracing`: ``` > sudo ./build/bin/linux/amd64/crictl --enable-tracing ps ``` Then jaeger should show collected traces and spans for the 3 RPCs `ListContainers`, `ImageFsInfo` as well as `Version`.
