Title:
  api slow due to missing LRP index

Status in neutron:
  In Progress
Status in ovsdbapp:
  Fix Released

Bug description:
  With many routers/Logical_Router_Ports the neutron-api can get slow at
  scale.

  When profiling the api we noticed that much time gets spend in
  functions like:

  sync_routers_and_rports -> _is_router_port_changed
  schedule_unhosted_gateways -> get_unhosted_gateways -> get_gateway_chassis_binding 
  schedule_unhosted_gateways -> get_gateway_chassis_az_hints 

  This happens due to LRP queries without an index:
    lrp = idlutils.row_by_value(self.idl, 'Logical_Router_Port', 'name', gateway_name)

  
  After adding an Logical_Router_Port name index the API performance improves a lot.
