Subject: [PATCH] Move iscsi helpers to brick directory.

This patch moves the iscsi helpers to the brick
directory.  We're doing this to enable the ability
to have a module/library of core block storage
functionality to use in other OpenStack projects.

After this the next step is to separate out the LVM
and iSCSI code in drivers/lvm.py and then to actually
have the Cinder LVM driver use the new brick LVM module.
