[Feature Request] dotnet trace should trigger based on namespace and frequency

In production, one typically has a focused suspect area to investigate. Tracing in a busy/noisy production environment would be far more very productive if we could express "trace from `Product.Module.SuspectMethod` and do that once every 600 seconds."

example

```
dotnet-trace collect --trigger=MyProduct.MyModule.MyMethod --interval=600
```

Additionally, one could have

`--interval-jitter=100` to avoid sample aliasing effects.
`interval=0` or missing the params: just trace once and be done
