Feature: Update kdm custom-analyzer command to be interactive

[utkarsh232005]

🎯 Goal

Convert the kdm custom-analyzer command from static add/list/remove CLI operations into an interactive rule manager with a table view and a guided creation wizard.

---

📌 Current Behavior

kdm custom-analyzer registers custom shell commands or HTTP webhooks to analyze arbitrary custom resources (CRDs).

Subcommands:

Subcommand	Description
kdm custom-analyzer add <name>	Register a new analyzer (--command or --url)
kdm custom-analyzer list	List all registered custom analyzers
kdm custom-analyzer remove <name>	Delete a registered custom analyzer

Example usage:

kdm custom-analyzer add keda --command "kubectl get scaledobjects -A -o json"
kdm custom-analyzer list
kdm custom-analyzer remove keda
