iPoid-Service provides a list of "risk types" associated with an IP address:
"UNKNOWN", "CALLBACK_PROXY", "GEO_MISMATCH", "LOGIN_BRUTEFORCE", "TUNNEL", "WEB_SCRAPING"
To support the work in T380708: Migrate account creation blocking logic to AbuseFilter and provide more anti-abuse capabilities in AbuseFilter, we should create a protected variable for ip_reputation_risk_types.
