Description

This is an easy way to improve security. See SOLR-14136

By default, access is allowed to all addresses, but if someone specifies a simple configuration to only allow local access and their own servers, such as:

SOLR_IP_WHITELIST="127.0.0.1, [::1], 192.168.0.0/24, [2000:123:4:5::]/64"

, then with a simple one-liner, things are a lot better than being open to everyone. Let's add something short and sweet to the ref guide security page.
