NFS does not use rootwrap for mount command

[Eric Harney]

It looks like NFS is no longer using rootwrap when running the mount command.

My guess is that this was introduced with https://review.openstack.org/#/c/43064 . Presumably affects GlusterFS as well but I haven't tried that.

    Remove default root_helper of sudo for remotefs

    This patch removes the default root_helper of sudo
    for the RemoteFsClient. We should be using the
    cinder.utils.get_root_helper()

    Fixes Bug #1223879
