nova-volume volume creation fails, tgt config not loaded

[Adam Gandelman]

Commit @ https://review.openstack.org/#/c/13633/ removes the explicit specification of volume config files to tgt-admin, and instead relies in tgt's configuration being set to find those config files in the appropriate place (nova's volumes directory). We've been shipping a file in /etc/tgt/nova_tgt to specify this directory and import all configs there, but it appears that it is not actually picking them up. With the --conf flag now removed, volume creation fails with tracebacks such as:

This bug was fixed in the package nova - 2012.2-0ubuntu3

---------------
nova (2012.2-0ubuntu3) quantal; urgency=low

  * nova-xvpvncproxy, nova-novncproxy: Add missing .install, .logrotate,
    .postrm, manpages and upstart jobs (LP: #1060336)
  * debian/{rules, nova-volume.install}: Rename nova_tgt to nova_tgt.conf so
    that it is actually loaded by tgt. (LP: #1060422)
