With the IPSec feature DHCP clients in starlingx no longer need to
request the options: domain-name-servers, and
dhcp6.name-servers.
The reason is that the management network is been migrated to a static
address configuration, with gateway and DNS servers provided to
the config files (ifcfg-* and resolv.conf) first by kickstart and
after by puppet manifest configuration.
The pxeboot network will use DHCP for initial bringup but it does not
need those options.
Test Plan:
[PASS] Install IPv4 Standard with storage
[PASS] Install IPv6 Standard with storage
