This commit raises the minimum TCP MSS clamping range to the MSS value
corresponding to the minimum packet size that must be accepted for IPv4.

* Refactor firewall and zone-policy rule creation and cleanup
* Migrate interface firewall values to `firewall interfaces <name> <direction> name/ipv6-name <name>`
* Remove `firewall-interface.py` conf script

Ability to get MTU from DHCP-server and don't touch it per
any interface change if interface 'dhcp-options mtu' is
configured

Directed broadcast is described in rfc1812#section-5.3.5.2 and rfc2644.
By default Linux kernel doesn't forward directed broadcast
packets unless both of `/proc/sys/net/ipv4/conf/all/bc_forwarding`
and `/proc/sys/net/ipv4/conf/$iface/bc_forwarding` are set to 1.

The sla-id parameter of DHCPv6 prefix delegations is limited to 128. While this
is enough to use all /64 subnets of a /57 prefix, with a /56 prefix that is no
longer sufficient.
Increased sla-id length tp 64535 so one could delegate an entire /48.

"set traffic-policy" now becomes "set qos policy"
"set interface ethernet eth0 traffic-policy" now bvecomes "set qos interface eth0"

Since introducing the XML <defaultValue> node it was common, but redundant,
practice to also add a help string indicating which value would be used as
default if the node is unset.
This makes no sense b/c it's duplicated code/value/characters and prone to
error. The node.def scripts should be extended to automatically render the
appropriate default value into the CLI help string.
For e.g. SSH the current PoC renders:
$ cat templates-cfg/service/ssh/port/node.def
multi:
type: txt
help: Port for SSH service (default: 22)
val_help: u32:1-65535; Numeric IP port
...
Not all subsystems are already migrated to get_config_dict() and make use of
the defaults() call - those subsystems need to be migrated, first before the new
default is added to the CLI help.

VXLAN does support using multiple remotes but VyOS does not. Add the ability
to set multiple remotes and add their flood lists using "bridge" command.

Commit 05aa22dc ("protocols: static: T3680: do not delete DHCP received routes")
added a bug whenever a static route is modified - the DHCP interface will
always end up with metric 210 - if there was a default route over a DHCP
interface.

* Migrates all policy route references from `ipv6-route` to `route6`
* Update test config `dialup-router-medium-vpn` to test migration of `ipv6-route` to `route6`

Both building blocks only differed in the help text, so use IP for both
IPv4 and IPv6.

Getting rid of "set firewall options" and move it from:
set firewall options interface ethX adjust-mss 1400
set firewall options interface ethX adjust-mss6 1400
to:
set interfaces ethernet ethX ip adjust-mss 1400
set interfaces ethernet ethX ipv6 adjust-mss 1400
In addition add an extra option called clamp-mss-to-pmtu instead of a value.

Some APNs require a username/password. Add CLI nodes (matching the PPPoE
syntax) for client authentication.
One APN would be the IPv4/IPv6 APN from Deutsche Telekom (Germany)
APN Name: Telekom Internet IPv6
APN: internet.v6.telekom
Benutzername: telekom
Passwort: tm

The previously used regex allowed an address value of "dhcpfoo" which is invalid
and will raise an OSError. Harden the regex that it explicitly must be dhcp or
dhcpv6.

Sometimes a modem might give a local IP before it retrieves a WAN IP.
This can be an issue with failover routes,
since the default route will get overridden.

VyOS 1.2 (crux) rejected prefixes other then of site /64.
[ interfaces ethernet eth0 ipv6 address eui64 2006:ab00:abe1::2/127 ]
Error: Prefix lenght is 127. It must be 64.
Same should be done on VyOS 1.3 and newer

As the amount of include files now has reached a certain amount, it is getting
more and more crowsded, thuse introducing "per topic" subdirectories on the
filesystem to keep a clean structure makes sense.
