Debugging connection issues can be extremely difficult, even more so at scale or when
concurrent connections are required to trigger specific issues.

Changes:
- Add a correlation identifier for each reconciliation, which allows for greater traceability when
going through all the reconciliation operations - including at transport level.
- Add transportType to segregate HTTP and SSH transport logging.
- SSH operations are now enriched with addr containing server address, and HTTP url.

GitRepository introduced correlation ID to improve
transport level logging. This change aligns the other
reconcilers to the same approach.
