* Port name sampler to containerd v2 (#7) (#11) * [tracing] Create NameSampler Simple sampler that samples every span having a certain name. It's best used in conjunction with the ParentBased sampler so that the child spans are also sampled. * [tracing] Configure otlp plugin to use NameSampler Allow the plugin to use the custom NameSampler if specified in the usual env vars used to specify the sampler `OTEL_TRACES_SAMPLER` and `OTEL_TRACES_SAMPLER_ARG`. This sampler will allow to avoid emitting a lot of the noisy traces to only keep a subset of meaningful traces.

On Kubernetes nodes this causes the kubelet to update node status subresources every time the order of runtime handlers changes in the status response from containerd. The lieklihood increases with the number of runtime handlers present on nodes. In some clusters this leads to every single node sending a status update every few seconds leading to excessive Kube API server load. This change enforces stable ordering on runtime handler names.

Update the dependency and the indirect golang.org/x/net version to align with containerd 1.7 itself, and to prevent a vulnerability being detected. This should not generally be an issue, as the API module is used by containerd 1.7 and up, which already depend on a more current version of these dependencies. full diff: containerd/ttrpc@v1.2.3...v1.2.5 Before this: govulncheck ./...
