iscsi: Establish connection to target via static target login

Browse Source 
https://bugzilla.redhat.com/show_bug.cgi?id=1356436

Commit id '56057900' altered the discovery of iSCSI node targets by
using the "--op nonpersistent". This caused issues for clean environments
or if by chance a "-m node -o delete" was executed.

Since each iSCSI Storage Pool has the required iSCSI target path, use
that and the virISCSINodeNew API in order to generate the iSCSI node record.
