Azure Fleet Tool Implementation

This pull request introduces a new az_fleet tool with structured parameters for managing Azure Kubernetes Service (AKS) Fleets. The implementation includes specialized command execution, parameter validation, enhanced error handling, and comprehensive documentation updates to improve usability, security, and maintainability.

New az_fleet Tool Implementation

The tool provides comprehensive Azure Kubernetes Service Fleet management capabilities with support for multiple operations across different resource types:

Supported Operations and Resources:

• fleet: list, show, create, update, delete
• member: list, show, create, update, delete
• updaterun: list, show, create, start, stop, delete
• updatestrategy: list, show, create, delete

Usage Examples:

• List fleets: operation='list', resource='fleet', args='--resource-group myRG'
• Show fleet: operation='show', resource='fleet', args='--name myFleet --resource-group myRG'
• Create member: operation='create', resource='member', args='--name myMember --fleet-name myFleet --resource-group myRG --member-cluster-id /subscriptions/.../myCluster'

Core Implementation Details

Fleet Executor Implementation: Added FleetExecutor in internal/azcli/fleet_executor.go to handle structured commands for az_fleet. This executor includes parameter validation, access level enforcement, and command construction capabilities.

Fleet Tool Registration: Updated internal/components/fleet/registry.go to register the az_fleet tool with structured parameters (operation, resource, args) and detailed descriptions for improved developer experience.

Testing Enhancements

Unit Tests for Executor: Added comprehensive tests in internal/azcli/fleet_executor_test.go to validate parameter extraction, access level enforcement, and command construction functionality.

Registry Tests: Enhanced tests in internal/components/fleet/registry_test.go to verify structured parameter registration and tool descriptions are properly configured.

Documentation Updates

README and Prompts: Updated README.md and prompts/azure-fleet-tools.md to reflect the new structured parameter approach. Documentation now includes practical examples and details about enhanced error handling and validation mechanisms.

Integration with Server

Server Integration: Modified internal/server/server.go to utilize the new FleetExecutor for executing az_fleet commands, ensuring seamless integration with the existing infrastructure.

Sample Usage

{
  "operation": "create",
  "resource": "updatestrategy",
  "args": "--name default --fleet-name fleet1 --resource-group fleet --stages /Users/test/github/aks-mcp/update-strategy.json"
}

{
  "operation": "list",
  "resource": "member",
  "args": "--fleet-name testhubfleet1 --resource-group hieunhu"
}

{
  "operation": "update",
  "resource": "member",
  "args": "--name akskeda-member --fleet-name testhubfleet1 --resource-group hieunhu --update-group group1"
}

These changes collectively enhance the functionality and user experience of the az_fleet tool while ensuring robust validation and security across all fleet management operations.
