    Add PD support in HA router
    
    The following enhancements are added:
      -- PD keeps track of status of neutron routers: active or
         standalone (master), or standby (not master),
      -- PD DHCP clients are only spawned in the active router. In the
         standby router, PD keeps track of the assigned prefixes, but
         doesn't spawn DHCP clients.
      -- When switchover occurs, on the router becoming standby, PD
         clients are "killed" so that they don't send prefix withdrawals
         to the DHCP server. On the router becoming active, PD spawns DHCP
         clients with the assigned prefixes configured as hints in the
         DHCP client's configuration
