Ihar Hrachyshka 469a1ca64b Don't instantiate RPC clients on import

In oslo.messaging port, we'll need to make sure no RPC clients or
servers or notifiers are created before RPC layer is initialized using
n_rpc.init(). This means that there should be no global objects that
create those objects on __init__.

There should also be no such class attributes because in that case
import will itself instantiate the object, probably before RPC layer is
ready.

Adds support for L3 routing/NAT as a service plugin

README

This service plugin implements the L3 routing functionality (resources router
and floatingip) that in earlier releases before Havana was provided by core
plugins (openvswitch, linuxbridge, ... etc).

Core plugins can now choose not to implement L3 routing functionality and
instead delegate that to the L3 routing service plugin.

The required changes to a core plugin are in that case:
- Do not inherit 'l3_db.L3_NAT_db_mixin' (or its descendants like extraroute)
  anymore.
- Remove "router" from 'supported_extension_aliases'.
- Modify any 'self' references to members in L3_NAT_db_mixin to instead use
  'manager.NeutronManager.get_service_plugins().get(constants.L3_ROUTER_NAT)'
  For example,
     self.prevent_l3_port_deletion(...)
  becomes something like
     plugin = manager.NeutronManager.get_service_plugins().get(
         constants.L3_ROUTER_NAT)
     if plugin:
         plugin.prevent_l3_port_deletion(...)

If the core plugin has relied on the L3Agent the following must also be changed:
- Do not inherit 'l3_rpc_base.L3RpcCallbackMixin' in any '*RpcCallbacks' class.
- Do not be a consumer of the topics.L3PLUGIN topic for RPC.

To use the L3 routing service plugin, add
'neutron.services.l3_router.l3_router_plugin.L3RouterPlugin'
to 'service_plugins' in '/etc/neutron/neutron.conf'.
That is,
service_plugins = neutron.services.l3_router.l3_router_plugin.L3RouterPlugin
