Added retry mechanism for interserver communication in ClickHouse when DNS errors occur.
Why it matters
This feature improves the reliability of interserver interactions by automatically retrying requests that fail due to DNS resolution errors. It helps prevent transient DNS issues from causing query failures or replication problems, enhancing overall system robustness.How to use it
The retry on interserver DNS errors is enabled by default to ensure seamless operation. Users do not need to perform any additional configuration to benefit from this feature.
