Disable s3_slow_all_threads_after_retryable_error by default

Why it matters

This change prevents all threads from being slowed down globally after encountering retryable errors on S3 storage. It improves performance and resource utilization by avoiding unnecessary throttling of threads when transient errors occur during S3 interactions.

How to use it

The s3_slow_all_threads_after_retryable_error setting is now disabled by default. Users can enable it explicitly in the ClickHouse server configuration if they want to apply thread slowing on S3 retryable errors by setting s3_slow_all_threads_after_retryable_error = 1.
