ionice not in rootwrap config

[Bryan D. Payne]

ionice may be executed by cinder as root:
https://github.com/openstack/cinder/blob/master/cinder/volume/utils.py#L155

however, it is not listed in the rootwrap config:
https://github.com/openstack/cinder/blob/master/etc/cinder/rootwrap.d/volume.filters

    Adds ionice command permutations to rootwrap filters

    When setting volume_clear_ionice, the ionice command is prepended to a dd
    command before executing it. Previously, this would have failed because it
    wasn't allowed through the default rootwrap filters. This commit fixes this
    problem.

    Note that due to the way that the RegExpFilter works, we need three different
    expressions to cover all cases. This is because the various options result
    in a different number of arguments. And this filter will fail immediately
    if the number of arguments is incorrect.
