Implement service map

[nascentcore-eng]

Is your feature request related to a problem? Please describe.
Right now we already have basic support for running eBPF+WASM module, but these modules are not very useful, i.e., they only provide tracing singular metrics and export them into PostgreSQL.

Describe the solution you'd like
We want to support service map, where we implement eBPF code to trace network traffic, and then parse them into protocol messages.

Then on top of the protocol messages, we derive the protocol messages between pods, services, etc. And export the data in OTel format.

Finally, we can build a service map on top of these OTel data.

Are you on Kubernetes, if so, what version
