Sascha Grunert f04bb71878 Tracing: sample always in hack/local-up-cluster.sh ...

If the feature gate `KubeletTracing` is enabled, then we should default
to a sample rate of 1 million per million, which will sample everything:

https://github.com/open-telemetry/opentelemetry-go/blob/aa868d5/sdk/trace/sampling.go#L107-L110

This helps to easier spin-up a cluster with tracing enabled by exporting
`FEATURE_GATES="KubeletTracing=true"`.
