How to make util_log.Logger.WithContext() always log TraceID

[ms-meya]

Hi Community,

Since cortex v1.11.0 util_log.Logger.WithContext() call tracing.ExtractSampledTraceID(ctx) instead of tracing.ExtraceTraceID(ctx) https://github.com/cortexproject/cortex/blob/v1.11.0/pkg/util/log/wrappers.go#L41.

And this tracing.ExtractSampledTraceID(ctx) (original commit @aknuds1 made) will check jaeger.SpanContext.IsSampled(), if it return false, util_log.Logger.WithContext() will not log TraceID, I want TraceID can be logged when util_log.Logger.WithContext() get called, I'm not familiar with jaeger tracing, how can I achieve that? Is there any configuration I can set to make this happen? Thank you!
