Today instrumentation code caches address of an endpoint

Recently this part was changed and multiple endpoints are possible. They are used in case of failure.
Please see this PR ClickHouse/clickhouse-java#2880

Describe the solution you'd like

• Context should have actual endpoint
• Failure is reported as some metric or just number of retries.
