    Install lvm2 for cinder-volume LVM hosts

    Currently the LVM2 package is installed by the
    openstack_hosts role for the integrated build,
    and by a test playbook for the role tests.

    This does not seem sensible to me - it would
    be better to ensure that the role installs the
    distro packages it need in order to function
    properly.

    Additionally, it is not possible to setup a
    loopback device inside an LXC container after
    some recent updates to LXC. The secondary
    cinder-volume service for LVM2 therefore
    does not work, so it is removed from the
    inventory to buy some time to come up with
    an alternative solution.
