L104 process = subprocess.Popen(cmd, stdout=subprocess.PIPE)

We need to add universal_newlines=True.

    Fix py3 issue in get_undercloud_registry()

    In python3 subprocess returns <class 'bytes'> type,
    in python2 this was <type 'str'>. Add universal_newlines
    argument to subprocess.Popen() call to ensure we get a
    string.
