[exporter/azuremonitor] Forward net.* attributes to Application Insights

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

I'm currently using the Azure Monitor exporter without much issue outside the outdated semconv attribute mappings, which I was able to fix, but I can't seem to find a way to make the Azure specific Client_* attributes map properly, they're present in the customDimensions under net.country, same with the user_agent, and yet, the ones appearing here are from the collector itself.
As a fair note, I AM pretty new to using otel on a standalone basis and I might just be missing what could be done through a processor.

Describe the solution you'd like

I think a good solution would either be a flag to map the attributes if present, or, as stated above, the use of a processor to remap things properly.

Describe alternatives you've considered

No response

Additional context

Here's a picture of what things look like in application insights:

As you can see, every single request is marked as coming from the netherlands, in the datacenter where I just so happen to host the collector. (You can't see it in this screenshot directly, but the customDimensons DOES hold all the data I'd like to be put at the root of the envelopes in their appropriate fields.)
