Add Body to net_packet_http

[tosbaha]

Documentation of net_packet_http_response talks about Response Body, but it looks like this doesn't actually print the Body. I checked the source code, and it seems the Body field is not there either. Is it possible to add Body to the request and response ? maybe with some kind of limit.

@yanivagman This is pretty simple to implement, we do have the info, it is a matter of adding it to the event or not. But does it make sense? As it might be a big string, not sure about limits for it, maybe, but it should be configurable as what interests one in the body is not the same as others, and a bigger limit would be needed. Or adding it doesn't make sense, and we should only drop it from the documentation for now?

I don't have a strong opinion about that.
Since we don't have event parameters yet, we can't let the user decide about the size of body to send from bpf code.
It is possible to set some arbitrary value of this limit for now, and possibly change it in the future
