Add k8s.rollout operation for checking deployment rollout status

[Cali0707]

Description

Add a k8s.rollout operation to check and manage deployment rollout status. This is needed for the rolling-update-deployment task which verifies that deployments complete their rollouts successfully.

Current bash tasks use patterns like:

• kubectl rollout status deployment/web-app -n namespace --timeout=120s

Requirements

• Support checking rollout status for Deployments
• Support checking rollout status for StatefulSets and DaemonSets
• Support timeout specification
• Return success/failure based on rollout completion

Example Usage

- k8s.rollout:
    apiVersion: apps/v1
    kind: Deployment
    metadata:
      name: web-app
      namespace: rollout-test
    timeout: 120s

Acceptance Criteria

• Can check rollout status for a Deployment by name and namespace
• Can check rollout status for StatefulSets
• Can check rollout status for DaemonSets
• Supports configurable timeout
• Returns success when rollout completes within timeout
• Returns failure with descriptive error when rollout fails or times out
• Operation is documented in extension manifest
