repeat registration when unload a bundle

[suiyuzeng]

Fixes #12165

Motivation

The bundle unloading of one producer or consumer will not affect other prodcers or consumers which belong to the same client and share the same connection.

If the bundle is unload when lookup, the server will send back error code ServiceNotReady. And the the client will close the connection in checkServerError.

    private void checkServerError(ServerError error, String errMsg) {
        if (ServerError.ServiceNotReady.equals(error)) {
            log.error("{} Close connection because received internal-server error {}", ctx.channel(), errMsg);
            ctx.close();
        } else if (ServerError.TooManyRequests.equals(error)) {
            incrementRejectsAndMaybeClose();
        }
    }

The other proudcers or consumers will be affected as they share the some connection. The request of the connection will be dropped and lookup.

Modifications

Replace the error code ServiceNotReady with ServerMetadata. The client will not close the connection, and other proudcers or consumers will not be affected.
