[AyushSriv06]

fix: #71
Add collect-info command for KubeSlice debug information collection

Summary
Implements kubeslice-cli collect-info command to gather comprehensive debug information
from KubeSlice components in Kubernetes clusters.

Changes

• Added cmd/collect-info.go - Main command implementation with Cobra framework
• Added pkg/collect-info.go - Orchestrates collection of debug information
• Added pkg/internal/collect-info.go - Core collection logic and kubectl operations
• Supports collection from: controller, worker, manager, calico, prometheus, resources
• Configurable collection types: logs, configs, events, metrics
• Outputs compressed .tgz archive for easy sharing and analysis

Testing
Tested on GKE cluster with KubeSlice 1.4.0 - Successfully collected debug info from
various components, handled error scenarios, and generated proper archive files. All
collection modes (logs, configs, events) working correctly with proper error handling.

Usage
kubeslice-cli collect-info -n kubeslice-demo --out debug-info.tgz
kubeslice-cli collect-info -n kubeslice-demo --components controller,worker --logs
