Public bug reported:

========== Problem Description ========
Currently, DHCP agent will get all active networks info (including subnets and its ports) from neutron server.
But, on a large scale, for example, if there have 2000+ networks, 2000+ subnets and thousands of ports. RPC
will be very very slow because of the message is too big so that time out for waiting for reply message.
