feat(auth): keep the client's system info at login

Browse Source 
After a successful login the auth server stores the system description the
client sent (memory text, video card, processor fields, Windows version fields)
exactly as sent, on the main thread with the login's other writes. The address
is only kept while log_login_addresses is on; log_client_sysinfo (on) turns the
whole thing off.
