hummingbot: Kucoin - Failed to query trading fees when its running on more than 10 trading pairs

Describe the bug According to Kucoin API doc, its endpoint for trading pair can only handle up to 10 trading pairs at a time. Reference as follows:
https://docs.kucoin.com/#actual-fee-rate-of-the-trading-pair

But current implementation _update_trading_fees from kucoin_exchange.py feeds all trading pairs in one call regardless of number of trading pairs from inputs. Therefore, the function raises an error when hummingbot is trading 10+ trading pairs on Kucoin.

Steps To Reproduce Run the following script base bot:

TRADING_PAIRS: Set[str] = set(
    [
        "XRP-USDT",
        "ARB-USDT",
        "USDC-USDT",

Propose Solutions I made a fix to this in my codebase:

    async def _update_trading_fees(self):
        trading_symbols = [
            await self.exchange_symbol_associated_to_pair(trading_pair=trading_pair)
            for trading_pair in self._trading_pairs
        ]
        fees_json = []
        for idx in range(0, len(trading_symbols), 10):
            tmp_trading_symbols = trading_symbols[idx : idx + 10]
            params = {"symbols": ",".join(tmp_trading_symbols)}
            resp = await self._api_get(
                path_url=CONSTANTS.FEE_PATH_URL,
                params=params,
                is_auth_required=True,
            )
            try:
                tmp_fees_json = resp["data"]
                fees_json.extend(tmp_fees_json)
            except KeyError as e:
                self.logger().error(f"Error fetching trading fees. Response: {resp}. Error: {e}.")
                raise e

        for fee_json in fees_json:
            trading_pair = await self.trading_pair_associated_to_exchange_symbol(symbol=fee_json["symbol"])
            self._trading_fees[trading_pair] = fee_json

I can make a PR to fix this if you agree
