Only KuCoin messages for 429000 error code are logged once.
Logs functions are also simplified and optimized.
test_remove_logs_for_pairs_already_in_blacklist is simplified as well.
More logs are reduced, for KuCoin, on the retrier_async decorator:
_async_get_candle_history() returned exception
retrying _async_get_candle_history() still for
Giving up retrying: _async_get_candle_history()
Applying DDosProtection backoff delay
KuCoin APIs generate A LOT of error messages.
Consequently, logs are flooded with lines like:
2021-12-25 22:30:23 freqtrade.exchange.common: WARNING -
_async_get_candle_history() returned exception:
"kucoin GET https://openapi-v2.kucoin.com/api/v1/market/candles?

429 Too Many Requests {"code":"429000","msg":"Too Many Requests"}"
Messages like:
Kucoin 429 error, avoid triggering DDosProtection backoff delay.
are logged only once for a certain period of time (default is 3600 seconds).
Every time that there's freqtrade "ticks", pairs in the blacklist are
checked and a warning message is displayed.
So, the logs are continuously flooded with the same warnings.
For example:
2021-07-26 06:24:45 freqtrade.plugins.pairlistmanager: WARNING -
Pair XTZUP/USDT in your blacklist. Removing it from whitelist...
2021-07-26 06:24:45 freqtrade.plugins.pairlistmanager: WARNING -
Pair SUSHIUP/USDT in your blacklist. Removing it from whitelist...
2021-07-26 06:24:45 freqtrade.plugins.pairlistmanager: WARNING -
Pair XTZDOWN/USDT in your blacklist. Removing it from whitelist...
2021-07-26 06:24:50 freqtrade.plugins.pairlistmanager: WARNING -
Pair XTZUP/USDT in your blacklist. Removing it from whitelist...
2021-07-26 06:24:50 freqtrade.plugins.pairlistmanager: WARNING -
Pair SUSHIUP/USDT in your blacklist. Removing it from whitelist...
2021-07-26 06:24:50 freqtrade.plugins.pairlistmanager: WARNING -
Pair XTZDOWN/USDT in your blacklist. Removing it from whitelist...
This patch shows the warning only the first time, by keeping track
of which pairs in the blacklist were already logged.
