Rename classes per review feedback

Changes requested by @dkropachev:
1. Renamed TLSSessionCache (ABC) to TLSSessionCacheBase in cluster.py
2. Renamed TLSSessionCacheOptions (ABC) to TLSSessionCacheOptionsBase in cluster.py
3. Renamed DefaultTLSSessionCacheOptions to TLSSessionCacheOptions in tls.py
4. Removed session_reused attribute from Connection class

Benefits:
- Clearer naming convention with "Base" suffix for abstract base classes
- Simpler naming for concrete implementations (no "Default" prefix needed)
- Reduced complexity by removing unused session_reused tracking
