Also, refactor ietadm/tgtadm calls out into helper classes. Add a new TargetAdmin abstract base class and implement it using ietadm and tgtadm. This cleans up the code greatly and gets us some code reuse. (Based on a patch by Chuck Short <zulcss@ubuntu.com>) Change-Id: I1c0064e5d35483a6c4059cfc61a484f5f576b2da
