Migrate "network list" command to new version using SDK.

This patch makes "network list" command use sdk.

Since we have to keep the other commands runnable with
the old network client, we use a temporary method to
create sdk network client. And as a result, the tests
need to patch a method to fake the temporary method,
which will be removed at last.
