    Make unicode-to-utf8 conversion universal in ceph backup driver.

    librbd does not like unicode strings. A patch was
    recently applied (c98cf2d8) to make all config
    values utf8 but there are other areas of the ceph
    backup driver where this also applies. This patch
    adds a new method which converts strings to utf8
    and replaces all relevant uses of str() with this
    new conversion.
