Persisting OpenStack iSCSI target configuration

[Mark McLoughlin]

Hey,

Just noticed this change in OpenStack Folsom over the weekend:

  https://bugs.launchpad.net/nova/+bug/1011159
  https://review.openstack.org/10414/

This means that iSCSI target configuration will be written
to /var/lib/nova/volumes and we'll need to include:

  include /var/lib/nova/volumes/*

in /etc/tgt/targets.conf.

This has a few implications for the Fedora packaging of Folsom:

  1) Need to package /var/lib/nova/volumes

  2) Probably need to have e.g. /etc/tgt/conf.d added to the default 
     /etc/tgt/targets.conf so that we can drop in a nova.conf

Cheers,
Mark.
