Aggregate Traces by Http Route

### Is there an existing issue for this?

- [x] I have searched the existing issues

### Is your feature request related to a problem? Please describe the problem.

When running aspire, I usually want to investigate the traces of a resource. Some of the resources have health checks that will run periodically and ping their dependencies. This results in bloating the traces view with traces I'm not particularly interested in. So I have then to carefully search for the traces I'm interested in, filter out the ones that are irrelevant, or pause the traces (great feature btw.).

### Describe the solution you'd like

It would be great to have the possibility (maybe even as default?) to aggregate the traces by Http Route (template)
