network configuration failed on reboot

Bug description:
[impact]
number of statically defined addresses for an interface in systemd-
networkd is limited
[test case]
Note: this only occurs in a container; this is not reproducable in a
VM or bare metal.
Configure netplan with the attached yaml file (10-test.yaml)
enable debug for systemd-networkd
reboot the system and check the journalctl output to see if any errors
were reported for systemd-networkd, e.g.:
$ journalctl -b -u systemd-networkd | grep 'could not set'
Jul 23 13:16:52 lp1930738-b systemd-networkd[189]: eth0: could not set
address: Connection timed out
...
Note that systemd may be able to actually correctly set all addresses,
but fails to communicate with netlink to determine the addresses are
set, so just checking the output of 'ip a' is not enough, the systemd-
networkd debug log should be checked
[regression potential]
possible failure to correctly apply all statically defined interfaces
[scope]
TBD, not fully fixed upstream
this is needed in f and b
this is fixed upstream with commits
628f08b66d43d1947b03419409d817d28eb47321 and PR 16982 which are
included in v246 and later, so this is fixed in h and later
[other info]
I elided upstream commit d31f33e3c9f6ea3bdc873ee52f4398edbec74527 as
that changes the udev-related behavior of networkd-manager inside a
container, which is not appropriate for SRU for this bug, as I don't
see any clear bug-related reason to change that behavior.
Additionally this requires the typo fix from commit
4934ba2121d76229659939e19ab7d70a89446629
[original description]
This issue was reported at
https://github.com/systemd/systemd/issues/17012
**Used distribution**
> Ubuntu 20.04.1 LTS
**systemd version the issue has been seen with**
> 245.4-4ubuntu3.2
**Issue details**
I configured 255 IPv4 address (including primary IP) using netplan but when
the server restart, it time out on configuring the interface. If I limit total
IPv4 addresses to 181 or less, it works. But anything larger than 181 fails.
Below are my configurations and error logs.
**/etc/netplan/10-ens3.yaml**
```
network:
version: 2
renderer: networkd
ethernets:
ens3:
dhcp4: no
addresses:
- 140.XX.XX.XX/23
- 103.XXX.XX.1/24
- 103.XXX.XX.2/24
- CONTINUED IP ADDRESS UPTO BELOW ...
- 103.XXX.XX.254/24
gateway4: 140.XX.XX.X
nameservers:
addresses: [1.1.1.1, 1.0.0.1]
routes:
- to: 169.254.0.0/16
via: 140.XX.XX.X
metric: 100
```
The above config works if I run `netplan apply` but when I reboot, it does
not work.
**networkctl**
```
