VDK IS AMAZING

[ewassef]

This pull request introduces several enhancements and new features, primarily focusing on improving configuration management, error handling, and Kubernetes integration. The most significant changes include the addition of a configuration management system, enhanced error handling in commands, and updates to Kubernetes namespace handling. Below is a detailed breakdown of the changes by theme:

Configuration Management

• Added ConfigManager class to handle loading, saving, and ensuring configuration, including prompting for a Tenant GUID and opening a browser for account creation if necessary (cli/src/Vdk/Services/ConfigManager.cs).
• Introduced VdkConfig model to represent configuration data such as TenantId and environment (cli/src/Vdk/Services/ConfigManager.cs).

Kubernetes Integration

• Added KubernetesConfigMapHelper to create a ConfigMap for storing cluster information (cli/src/Vdk/Services/KubernetesConfigMapHelper.cs).
• Updated ReverseProxyClient to handle the vega-system namespace instead of vega, including creating or updating a ConfigMap for cluster information after Flux bootstrap (cli/src/Vdk/Services/ReverseProxyClient.cs). [1] [2] [3] [4]

Error Handling Enhancements

• Added try-catch blocks with error logging in the InvokeAsync methods of CreateRegistryCommand, RemoveRegistryCommand, and RemoveProxyCommand to handle exceptions gracefully (cli/src/Vdk/Commands/CreateRegistryCommand.cs, cli/src/Vdk/Commands/RemoveRegistryCommand.cs, cli/src/Vdk/Commands/RemoveProxyCommand.cs). [1] [2] [3]

Command Improvements

• Enhanced CreateClusterCommand and InitializeCommand to ensure configuration exists before proceeding, using the new ConfigManager (cli/src/Vdk/Commands/CreateClusterCommand.cs, cli/src/Vdk/Commands/InitializeCommand.cs). [1] [2]
• Updated CreateClusterCommand to accept a Func<string, IKubernetesClient> for dynamic Kubernetes client creation (cli/src/Vdk/Commands/CreateClusterCommand.cs).

Testing Infrastructure

• Added a CommandTestBase class with mock support for IConsole to simplify unit testing for commands (cli/tests/Vdk.Tests/CommandTestBase.cs).
