Description

Add CDC agent for Cassandra 5.0 support

Adds a complete CDC agent implementation for Apache Cassandra 5.0. Currently cdc agent does not work on Cassandra 4.1+ or Cassandra 5.0+ due to issues mentioned in #180. This includes a new agent-c5 module with Cassandra 5.0-specific CDC handling, addressing API changes and compatibility issues between Cassandra 4.0 and 5.0.

Consideration

Cassandra 4.1 and 5.0 introduced breaking changes in internal APIs that the CDC agent relies on. This creates a dedicated agent implementation that handles the new APIs while maintaining the same CDC functionality.

Changes

• New agent-c5 module with complete CDC implementation for Cassandra 5.0
• Updated CommitLogReadHandler to work with Cassandra 5.0 internal APIs
• Java 11, 17 compatibility with required JVM exports/opens for Cassandra 5.0
• Docker configuration for Cassandra 5.0 CDC containers
• Test suite with integration tests for single and dual node setups
• Updated build configuration to support Cassandra 5.0.4
