Title:
  dhcp_agents_per_network does not work appropriately.

Status in OpenStack Neutron (virtual network service):
  Incomplete

Bug description:
  Hi,

  I want to ask about dhcp_agents_per_network option in neutron.conf.

  That's instruction is in neutron.conf
  -----
  # Number of DHCP agents scheduled to host a network. This enables redundant
  # DHCP agents for configured networks.
  # dhcp_agents_per_network = 1
  dhcp_agents_per_network = 1
  -----

  I hit situation that network is hosted by multiple dhcp-agents evenif dhcp_agents_per_network = 1.
  I think dhcp_agents_per_network does not work appropriately.

  The procedure are as follows.

  Conditions:
    A) multiple network nodes.
    B) dhcp-agents are alives in each network nodes.
    C) one network is hosted by one dhcp-agent.

     ex:
       network node1:  dhcp-agent1 hosts network1 and network2.
       network node2:  dhcp-agent2 hosts no network.

  procedures:

  1)  stop dhcp-agent1 and dhcp-agent2.
  2)  start dhcp-agent2.

  result:

       network node1:  dhcp-agent1 hosts network1 and network2.
       network node2:  dhcp-agent2 hosts network1 and network2.

  dnsmasq hosting network1 boots on network node1 and 2.
  also, dnsmasq hosting network2 boots on network node1 and 2.

  dhcp_agents_per_network option means "active_dhcp_agents_per_network"
  or "dhcp_agents_per_network"?
