Summary of Changes

Hello @DSFans2014, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request integrates a mock-device-plugin into the hami Helm chart, providing a flexible solution for testing and development environments. It sets up all necessary Kubernetes resources, including a DaemonSet for deployment, a ServiceAccount, and appropriate RBAC permissions, along with Helm templating for easy configuration and management.

Highlights

• Helm Template Additions: New helper templates have been introduced in _helpers.tpl for consistent naming and image definition of the mock-device-plugin.
• Mock Device Plugin Deployment: A new DaemonSet (daemonsetmock.yaml) has been added to deploy the mock-device-plugin across the Kubernetes cluster, enabling its conditional activation via Helm values.
• RBAC Configuration: Dedicated ServiceAccount, ClusterRole, and ClusterRoleBinding resources have been created for the mock-device-plugin to ensure it has the necessary permissions to interact with Kubernetes nodes and pods.
• Configuration Options: The values.yaml file now includes a mockDevicePlugin section, allowing users to enable/disable and configure the image details for the mock device plugin.

Code Review

This pull request introduces a mock-device-plugin to the Helm chart. The implementation is mostly sound, adding the necessary Kubernetes manifests and values. However, I've identified a bug where an incorrect imagePullPolicy is used for the new plugin's container. Additionally, there are a couple of inconsistencies in code style and label usage that should be addressed to improve maintainability and align with the rest of the chart. My review includes specific suggestions to resolve these issues.
