Enhance Status Reporting for Tratteria Custom Resources

[kchiranjewee63]

Current Behavior

Tratteria CRDs currently provide limited status information. For example, TraTs only show two states: PENDING and DONE. This minimal status reporting limits visibility into the resource's lifecycle and potential issues.

Desired Behavior

Implement a more elaborate and informative status reporting system for Tratteria CRDs, providing detailed information about the resource's state, progress, and any issues encountered.

Example of Current Status (TraT)

Status:
  Generation Applied:    true
  Retries:               0
  Status:                DONE
  Verification Applied:  true

Some Potential Status Fields (non-exhaustive)

• observedGeneration: The latest generation observed by the controller.
• phase: A high-level summary of the resource's current state (e.g., "Pending", "PartiallyApplied", "Applied")
• components: Status of individual components or stages, e.g.:
  • verification: Status of the verification rule propagation (e.g., "Pending", "PartiallyApplied", "Applied")
  • generation: Status of the generation rule propagation (e.g., "Pending", "PartiallyApplied", "Applied")
• lastSuccessfulUpdate: Timestamp of the last successful update
• errors: An array of any errors encountered during processing

Discussion Points

• What additional status fields would be useful for operators and developers?
• Should we implement a condition-based status similar to other Kubernetes resources?

Affected Resources

• TraT
• TratteriaConfig
• TraTExclusion
