The daemon uses firewalld only if firewalld is running when the daemon
starts. If firewalld is started later, the daemon does not react to it
starting or reloading. On firewalld configurations which delete other
applications' iptables rules when firewalld starts, the daemon's rules
stay deleted. The daemon's bridges are not added to the docker zone.
Keep the D-Bus connection when firewalld is not running at startup.
When firewalld acquires its D-Bus name, set up the docker zone and
forwarding policy before running the reload callbacks.
