Do domain resolution for portal (#461)

* Do domain resolution for portal

iscsiadm support domain resolution (ex: iscsiadm -m discovery -t sendtargets -p iscsi.chiehmin.com).
However, open_iscsi module will try to match the portal with discovered results which will never
matched cause the discovered results use IP to represent node.

This patch do portal DNS resolution first to solve this situation.
