Pull request overview

This PR adds support for Weaviate's Object Time-To-Live (TTL) feature, which allows automatic expiration and deletion of objects based on time criteria. The implementation provides three TTL strategies: deletion by creation time, deletion by update time, and deletion by a custom date property.

Key changes:

• Added _ObjectTTL and _ObjectTTLCreate classes for configuring TTL behavior
• Integrated TTL configuration into collection creation and management APIs
• Added support for parsing TTL configuration from Weaviate schema responses
