fix(gnmic): rewrite config with correct parameters and simplified paths

Browse Source 
- Remove invalid 'add-target: target' (must be overwrite|if-not-present|empty)
- Enable debug mode for troubleshooting
- Simplify interface paths to /interfaces/interface/state (Arista compatible)
- Simplify system paths to /system/state
- Remove complex BGP path that may not work on cEOS
- Add retry and timeout parameters for reliability
- Add expiration to prevent stale metrics
- Add skip-verify for insecure connections
- Increase sample intervals for stability
