Add firewall address-sets: named sets of IP addresses and networks,
usable as zone sources for per-IP access control, issue #1189. Static
entries are part of the configuration; dynamic entries are managed at
runtime with new add/remove/flush actions, from the CLI or over
NETCONF/RESTCONF. Dynamic entries survive firewall configuration
changes but are not saved to the configuration. Sets with a timeout
expire their entries automatically.

This fixes the following log message on systems w/o firewall enabled
dumping operational data:
Dec 2 09:24:57 test-00-02-00 yanger[5352]: Failed to connect to firewalld D-Bus: org.freedesktop.DBus.Error.ServiceUnknown: The name org.fedoraproject.FirewallD1 was not provided by any .service files

Add supoprt for infix-firewall.yang, modeled on the zone-based firewalld
The terminology is a mix of firewalld, classic netfilter and inspired by
Ubiquity. E.g., zone 'policy' -> 'action', and the zone matrix overview.
- Port forwarding allows forwarding a range of ports
- Operational data comes from firewalld active rules
- Firewall logging goes to /var/log/firewall.log
- Show implicit/built-in rules and zones (HOST) in firewall matrix,
includes "locked" policy for the default-drop behavior
- The zone services field in admin-exec 'show firewall' shows ANY when
the zone default action is set to 'accept'
- Zone 'forwarding' and 'masquerade' settings live in Infix in the
policys instead, meaning users need to explicitly add a policy
to allow both intra-zone and inter-zone forwarding
- Support for emergency lockdown (kill switch)
- Pre-defined services (xml+enums) are filtered and included as a
separate YANG model, extensions added for netconf and restconf
- Includes initial support for firewalld rich rules
firewalld policy rules, including rich rules, have an obnoxious priority
field which is extremely hard to get right, so in Infix we use the far
superior YANG construct 'ordered-by user;'. This ensure all rules are
generated in that order by setting the priority field, on read-back from
firewalld (operational) the priority field is used to sort the output
of rules in the CLI.
