    Add retry to lvm snapshot create

    We have some occasional issues with snapshot-create
    failing for what looks to be conflicts with udev. It
    looks like this problem is a status conflict between LVM
    cache and udev, and in most cases the best way to get
    around this is to retry the command a few times until
    the cache and udev are back in sync.

    This patch uses the newly added retry decorator and
    for now we're just adding it to the snapshot create
    call. We're using the default values for interval and
    retry count but we can certainly adjust this as needed.
