    DHCP: fix regression with DNS nameservers
    
    The commit 3686d035ded94eadab6a3268e4b0f0cca11a22f8 caused a
    regression for setups that support a number of DNS servers that
    are injected via the DHCP options 5 and 6.
    
    If the dnsmaq has a configured dns-server then it will ignore
    the ones that are injected by the admin. That is what the commit
    above did. This causes a number of problems. The main one is that
    it requires the DHCP agent to have connectivity to the DNS server.
    
    The original code was added in commit
    2afff147c45f97a0809db40ad072332fb37ccd8d

Title:
  DHCP: when upgrading from icehouse DHCP breaks

Status in neutron:
  Fix Released

Bug description:
  When upgrading the J, K or any other version the DNS support break. 
  That is, the DHCP agent has the option for setting DNS servers, this is via the the options dnsmasq_config_file=/etc/neutron/myconfig.ini
  Where myconfig will have support for the following:
  dhcp-option=5,2.4.5.6,2.4.5.7
  dhcp-option=6,2.4.5.7,2.4.5.6

  In the guest /etc/resolve.conf we see the DHCP address and not the
  configured IP's

  The reason for this is
