feat: enhance connector interface and implementations (#2675)
- Updated the Connector interface to return both stdout and stderr for command execution.
- Modified implementations in local, kubernetes, and ssh connectors to support the new return values.
- Improved documentation for the Connector interface methods for clarity.
- Added error handling for stderr in command execution across connectors.
- Introduced new utility functions for IP parsing and checking localhost IPs.
