test/iscsi_tgt: Test login redirection 



Run two iSCSI target applications, the first application has a
public portal 10.0.0.1:3260 and the second application has a private
portal 10.0.0.3:3260.

Each application creates a target which has the corresponding portal
and a NULL bdev. The NULL bdev has the same configuration between
two applications.

By using NULL bdev, we do not have to worry about shared storage.

Then move between two portals by using temporary login redirection
function.

We tried to differentiate only TCP port but such idea did not work
with the popular iSCSI initiator, open-iscsi.
