    nova: configure file injection by the means of config drive

    We've seen a number of problems with qemu-nbd (from files not being
    injected randomly to kernel panics), and while libguestfs is a
    better solution here it does not work out of box on Ubuntu. Neither
    of these can be used for file injection when instance ephemeral
    drives are stored in Ceph.

    Disabling of file injection in Nova libvirt drive allows us to unify
    the settings for Ubuntu vs CentOS and file vs Ceph-based ephemerals.
    In this case file injection ban still be performed by the means of
    config drive + cloud-init within images.

    Upstream Nova / Devstack explicitly disabled file injection in favor
    of using config drives in:
