Integrate BACKBEAT SDK and resolve KACHING license validation

Major integrations and fixes:
- Added BACKBEAT SDK integration for P2P operation timing
- Implemented beat-aware status tracking for distributed operations
- Added Docker secrets support for secure license management
- Resolved KACHING license validation via HTTPS/TLS
- Updated docker-compose configuration for clean stack deployment
- Disabled rollback policies to prevent deployment failures
- Added license credential storage (CHORUS-DEV-MULTI-001)

Technical improvements:
- BACKBEAT P2P operation tracking with phase management
- Enhanced configuration system with file-based secrets
- Improved error handling for license validation
- Clean separation of KACHING and CHORUS deployment stacks

+## Documentation
+
+See https://godoc.org/github.com/libp2p/go-libp2p-record.
+
+## Testing
+
+This package has some tests that rely on generating weak RSA keys (for speed).
+In order to successfully run the tests, one must set the environment variable,
+`LIBP2P_ALLOW_WEAK_RSA_KEYS` to any non-empty value, such as `1`.
