Azat Khuzhin e37e8f83bb Fix flakiness of test_distributed_load_balancing
I saw the following in the logs for the failed test:

    2023.05.16 07:12:12.894051 [ 262 ] {74575ac0-b296-4fdc-bc8e-3476a305e6ea} <Warning> ConnectionPoolWithFailover: Connection failed at try №1, reason: Timeout exceeded while reading from socket (socket (172.16.3.2:9000), receive timeout 2000 ms)

And I think that the culprit is the
test_distributed_replica_max_ignored_errors for which it is normal,
however not for others, and this should not affect other tests.

So fix this by calling SYSTEM RELOAD CONFIG, which should reset error
count.
