Use .format() in `cef` logging function

Split rule generation to separate function

Using a dedicated function prepares the ground for ipset and ipv6 support.

conntrack, and we only match the first packets of the connections.

IPSet support

If a destination is a simple CIDR, without port and protocol, then add it into
an ipset specific to the user. This ipset is looked up at the top of the user's
iptables custom chain.
Discard duplicated ACLs

If a destination CIDR is listed multiple times in LDAP, only use the first occurence.
