    Removes unicode 'u' response from "glance image-tag-update"

    "glance image-tag-update" command returns unicoded response
    for lists. Therefore it requires print_list method from util
    class to handle such case. Added unicode_key_value_to_string()
    method to remove extra 'u' from lists and dictionaries. This
    fix is inspired from cinderclient's implementation.
