    Expose max request and secret size config options.

    Upstream Barbican has bumped up its default for the configuration keys
    max_allowed_request_size_in_bytes and max_allowed_secret_in_bytes to
    25kB and 20kB respectively (c59f2a6b). This change adopts those values
    to be used in all the supported releases and exposes them via juju
    config.
