Logical systems: DNS sinkhole enhancements

As part of the DNS sinkhole feature enhancements, you can: 

• Configure new actions for a DNS request for a disallowed domain-alert, accept, drop, and dropno-log. 
• Configure domain names and actions for multiple tenants such that domain feeds can be managed on a per tenant basis. 
• Configure hierarchical domain feed management per profile, dns-filter-template or dns-filter-term. 
• Exempt domain feeds at the IP, subnet, or CIDR level.
