Title:
  neutron-dhcp-agent send 0x03 dhcp flag to a client

Status in neutron:
  New

Bug description:
  If the client is a virtial host with Window introduced in the AD domain. The client does not send dns updates on AD server because neutron-dhcp-agent sends 0x03 dhcp flag in response. 
  Client request:

  Option: (81) Client Fully Qualified Domain Name
  Length: 23
  Flags: 0x00
  0000 .... = Reserved flags: 0x00
  .... 0... = Server DDNS: Some server updates
  .... ..0. = Server overrides: No override
  .... ...0 = Server: Client
  A-RR result: 0
  PTR-RR result: 0
  Client name: dnstest.local

  Server respose:

  Option: (81) Client Fully Qualified Domain Name
  Length: 30
  Flags: 0x03
  0000 .... = Reserved flags: 0x00
  .... 0... = Server DDNS: Some server updates
  .... .0.. = Encoding: ASCII encoding
  .... ..1. = Server overrides: Override
  .... ...1 = Server: Server
  A-RR result: 255
  PTR-RR result: 255
  Client name: host-172-25-43-40.local

  Because of this windows host does not send update dns requests on AD
  server and after certain time out server remove client hostname from
  DNS zone.
