This patch makes "network show" 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.
There are two same test cases in the unit tests. This
patch will remove one.
And since the output has changed, we also need to fix
function test cases.
