Add `systemd.network.networks.*.dhcpServerStaticLeaseConfig` to allow for configuring static DHCP leases through the `[DHCPServerStaticLease]` section. See systemd.network(5) of systemd 249 for details. Also adds the NixOS test `systemd-networkd-dhcpserver-static-lease` to test the assignment of static leases.
