Send additional fields from ebpf-discovery: url-scheme, domain

[lnarolski]

eBPF-discovery should send additional information in each json:

• URL scheme in text format (currently only “http” or “https”)
• domain (from “Host:” header) - for now, we only have the resulting IP.
  If we accidentally have IP in the header, it’s ok, don’t do reverse DNS
