Support "network list" command in nova network

"network list" command is not implemented in nova network.
This patch implements it.

The Network object in novaclient is quite different from
the one in sdk. And the output of "network list" using
Nova network is also quite different from using Neutron.

It is like this:

# openstack network list
+--------------------------------------+---------+-------------+
| ID                                   | Name    | Subnet      |
+--------------------------------------+---------+-------------+
| 96a98ec4-31f6-45f6-99e6-9384569b3bb5 | private | 10.0.0.0/24 |
+--------------------------------------+---------+-------------+

--long and --external options have not been implemented because
the attrs in Network object in novaclient is too much different.

This patch also introduces a new FakeNetwork class in compute/v2/fake.py
to fake nova network.
