by using both a namespace and uuid of router

When I create a router, I add a specific name attribute of the router. So We can use both the uuid and namespace in the below case.
quantum router-create --tenant-id $put_id_of_project_one <router_name>
root@nova3:~# quantum router-list
+-----------------------------------------------+----------------+-----------------------+
| id | name | external_gateway_info |
+-----------------------------------------------+----------------+-----------------------+
| e449e76b-33e9-47ff-8d6a-7efcdd3a0e9b | router_grizzly | null |
+-----------------------------------------------+----------------+-----------------------+

In current method:
    - When "ip netns list" in network node searched, it is not easy to know about router. Because It is viewed as the router ID.

    root@nova4:~# ip netns list
        qdhcp-41baaaea-8ddc-443e-a890-9a47610dac9f
        qrouter-e449e76b-33e9-47ff-8d6a-7efcdd3a0e9b

In new method:
    - When "ip netns list" in network node searched, it is easy to know about router. Because It is viewed with the preset name alias of router
        root@nova4:~# ip netns list
        qdhcp-41baaaea-8ddc-443e-a890-9a47610dac9f
        qrouter-router_grizzly
