It makes more sense to call VXLAN ID as
1. the VXLAN Network Identifier (VNI) (or VXLAN Segment ID)
2. test-network: rename VXLAN Id to VNI
3. fuzzer: Add VXLAN VNI directive to fuzzer
Because of this the fd is getting closed and we getting errors
like
```

We not stopping the clients when networkd stops. They
should shut down cleanly and then we need to clean the DS.
One of requirements to implement

1. When the DHCPv4 lease expires kernel removes the route. So add it back
when we gain lease again.
Closes https://github.com/systemd/systemd/issues/12426
2. When UseRoutes=false do not remove router
Media Access Control Security (MACsec) is an 802.1AE IEEE
industry-standard security technology that provides secure
communication for all traffic on Ethernet links.
MACsec provides point-to-point security on Ethernet links between
directly connected nodes and is capable of identifying and preventing
most security threats, including denial of service, intrusion,
man-in-the-middle, masquerading, passive wiretapping, and playback attacks.
Closes#5754
Now we are not dropping the IPv6LL address when link is down.
So next time when link is up and before kernel acquired this address
we are using the old address.
When the link is down kernel tells us that this address is no longer
valid . Let's remove this address and again when kernel tells us
that the address is added let's use it.

networkd: add support to set route table
1. add support to configure the table id.
if id is less than 256 we can fit this in the header of route as
netlink property is a char. But in kernel this proepty is a
unsigned 32. Hence if greater that 256 add this as RTA_TABLE
attribute.
2. we are not setting the address family now. Now set this property.
Introduce
1. sd_rtnl_message_route_set_table to set table ID
2. sd_rtnl_message_route_set_family to set family
Both required to configure route properties.
We are not able to add multiple properties.

[Match]
Name=wlp3s0
[Route]
Gateway=10.68.5.26
Metric=10
sudo ./systemd-networkd
Failed to parse file '/usr/lib/systemd/network/wlp3s0.network': File

This patch fixes it.
Added sd_rtnl_message_append_u8 and
few attribute support in sd_rtnl_message_append_u32
IFLA_GROUP, IFLA_TXQLEN, IFLA_NUM_TX_QUEUES, IFLA_NUM_RX_QUEUES
