[PR] [client][rust] Retry bootstrap initialization on retriable errors [fluss]

slfan1989 opened a new pull request, #3758:
URL: https://github.com/apache/fluss/pull/3758

   ### Purpose
   
   Linked issue: close #3744
   
   The Rust client currently fails immediately when initialization against a single bootstrap server encounters a temporary retriable error.
   
   This change aligns the Rust client with the Java client by retrying bootstrap initialization when the configured bootstrap server is temporarily unavailable or recovering.
   
   ### Brief change log
   
   - Retry initialization for a single bootstrap server on retriable errors.
   - Perform up to three retries with exponential backoff of 100 ms, 200 ms, and 400 ms.
   - Evict the cached RPC connection before each retry so that the next attempt establishes a fresh connection.
   - Return non-retriable errors immediately without retrying.
   
   ### Tests
   
   Added unit tests.
   
   ### API and Format
   
   This change does not affect the public API or storage format.
   
   ### Documentation
   
   No documentation changes are required.
