name-server: T3804: merge "system name-servers-dhcp" into "system name-server"
We have "set system name-server <ipv4|ipv6>" to specify a name-server IP address we wan't to use. We also have "set system name-servers-dhcp <interface>" which does the same, but the name-server in question is retrieved via DHCP. Both CLI nodes are combined under "set system name-server <ipv4|ipv6|interface>" to keep things as they are in real life - we need a name-server. (cherry picked from commit 2ecf7a9f9cbe9359457bd23b4a0c45f3763123c7)
