Introduce client.metadata.retry.times/client.metadata.retry.interval configurations

Search before asking

• I searched in the issues and found nothing similar.

Motivation

When the current client starts up and retrieves metadata, the number of connection retries and the interval are fixed values（MetadataUpdater::MAX_RETRY_TIMES, MetadataUpdater::RETRY_INTERVAL_MS）. Making this part configurable would be more flexible.

The metadata mechanism will be refactored later, and this feature may no longer be needed after the refactoring.
