Fix py3 compatibility
In fetch_and_sync_all_routers method is used python's range function.
Range function accepts integers.
This patch is fixing divide behaviour in py3 where result number is float,
by retyping float to int as it is represented in py2.

Problem is in neutron/agent/l3/agent.py when py3 is used in code of
block where "range" is used :
757 for i in range(0, len(router_ids), self.sync_routers_chunk_size):
758 chunk = router_ids[i:i + self.sync_routers_chunk_size]
This can be fixed by this patch >>
