The name with plural made more sense where multiple options could be specified
in one line. After changes in the pull request, this option only accepts one
value, so from users' POV it should be singular.
(The field in the data structure remains plural, because it actually stores
multiple values.)

networkd: drop DHCPv4 config on stop, keep on restart, by default
...
This partially reverts 95355a281c
.
It seems that other parts of link_stop_clients() should be skipped
when restarting, but I don't know enough about those other clients to have
an opinion if it is better to stop&start them on restart or not.
Anyway, that can be done in later patches now that the support for restarts
is there.
Fixes #13625 .

dhcp4: make IPServiceType configurable
...
IPServiceType set to CS6 (network control) causes problems on some old
network setups that continue to interpret the field as IP TOS.
Make DHCP work on such networks by allowing this field to be set to
CS4 (Realtime) instead, as this maps to IPTOS_LOWDELAY.
