As part of the Podman 6 release, we need to remove the BoltDB backend for state management. BoltDB has been replaced with SQLite, which provides better performance and reliability.

This story involves:

• Removing BoltDB code and dependencies from podman and c/common components
• Updating documentation to reflect the removal
• Ensuring all functionality works correctly with SQLite only
• Updating tests to remove BoltDB-related test cases
