Make WithDistributedTracingOptions() available in preview

[mortenbock]

Is your feature request related to a problem? Please describe.
When running the -preview package, the distributed tracing is logging a lot of traces for requests over the default LatencyTreshold. We cannot change these thresholds because DistributedTracingOptions and WithDistributedTracingOptions() are internal.

Describe the solution you'd like
Make the relevant API's public for -preview, so we can decide the latency threshold we prefer.

Describe alternatives you've considered
We considered a TelemetryProcessor for AI to detect and remove these traces, but decided to disable the distributed tracing for cosmos altogether instead.

Additional context
We are using Application Insights for out application.

Thanks for asking for it.

We are working on it, you would see this option available in next version of preview SDK. Although API name would be changed.
