    Do not quote '+' for token header

    The token in request header may contain url char, such as '+',
    if quote it, '+' will change to '%2B' which will lead to 401 error.

    Our CI doesn't notice this bug because Keystone use fernet token
    which doesn't contain url char by default. But token format in
    keystone is plugable, some out-tree token formats may contain
    url char (for example, PKI/PKIZ token).

    So we should skip quote token to avoiding information changing.
