The RPC L3 agent clients and servers should be instantiated and initalizated during the ``Service`` start phase, not during the class initalization. The L3 agent main class is handled by the ``oslo_service.Service`` class as the manager class. When the process (L3 agent) is started, the service class forks the process during the ``service.launch`` call [1]. That could lead to issues with the created RPC client/servers before the fork [2]. This patch moves all the RPC instantiation and initialization to the ``Service.start`` method, that first calls the manager ``init_host`` method. This patch must work both with the current ``oslo.service`` backend (eventlet) and the future implementation (threading) [3].
