Maybe pass ProcessMemoryDump* here, with a root name as
"net/url_request_context_X/media_X"

You can add extra id from here and create allocator dump:

name = root_name + "/http_request_X"
pmd->createDump(name);

+  std::string name = base::StringPrintf("http_network_session_%p", this);
+  //base::trace_event::MemoryAllocatorDumpGuid guid(name);

+        dump->guid(), http_network_session_dump->guid());
+    return;
+  }
+  http_network_session_dump = dump->process_memory_dump()->CreateAllocatorDump(
+      name);
+  normal_socket_pool_manager_->PopulateAllocatorDump(http_network_session_dump);

The code could be:

name = root_name + "/http_request_X"
dump = pmd->createDump(name);
dump->AddScalar(size);

target_name = "net/url_request_context/all_http_sessions/session_X"
target_dump = pmd->GetAllocatorDump(target_name);
if (!target_dump) {
  target_dmup = pmd->GetAllocatorDump(target_name)
  target_dump->AddScalar(size);
}
// This will take the effective_size away from the 
// "all_http_sesisons" pool and give it to the media/ dump.
pmd->AddOwnershipEdge(dump, target_dump);
