    DHCP Agent: Separate local from non-local subnets
    
    In order to allow the DHCP agent to service other subnets on the
    network in other segments via DHCP relay, we need to use the
    'non_local_subnets' network attribute returned by rpc to set up dhcp
    for off-link subnets.

Title:
  [RFE] Neutron Segments DHCP-relay support

Status in neutron:
  Fix Released

Bug description:
  When using Neutron Segments we would like dhcp agent to configure DHCP
  servers to serve clients on remote(non-local) subnets. The remote(non-
  local) subnet will need to have a DHCP-relay/forwarder configured. The
  relay agent will run on ToR switch or router in the routed underlay
  network and would be configured by the operator, it does not need to
  be managed by neutron.

  Currently the Neutron Segments implementation expect a DHCP agent to
  be available on all segments, and thus non-local subnets are filtered
  in dhcp_rpc to return only subnets local to the agent.

  To support DHCP relay we need to return all subnets and inform the
  DHCP agent wich subnets are local vs non-local so that the DHCP agent
  will only bind port/ip-address to the subnets that is local.

  Implementation of the dhpc_rpc part of this has been started with these reviews:
