Fix creation of iscsi targets
Fix creation of iscsi targets

Previously when creating iscsi volumes, we were using

tgt-admin -e -c <config file> --update volume-id

Unfortunately the side affect of this is that tgt-admin
removed other volumes that wasnt connected to an iscsi
connector. Which is obvlously not what we want.

In order to fix this we create the targets.conf for the
volume but we call tgt-admin --update icssi qualified name.
We also set the tid in the configuration file now as well.

Fixes LP: #1038062
