feat(sdk): ✨ Complete Phase 2 - AppInstance, Cloudlet APIs & CLI integration
Implemented comprehensive EdgeXR SDK with full API coverage and CLI integration:
## New API Coverage:
- **AppInstance Management**: Create, Show, List, Refresh, Delete instances
- **Cloudlet Management**: Create, Show, List, Delete cloudlets
- **Cloudlet Operations**: GetManifest, GetResourceUsage for monitoring
- **Streaming JSON**: Support for EdgeXR's multi-line JSON response format
## API Implementations:
### AppInstance APIs:
- CreateAppInstance → POST /auth/ctrl/CreateAppInst
- ShowAppInstance → POST /auth/ctrl/ShowAppInst
- ShowAppInstances → POST /auth/ctrl/ShowAppInst (multi-result)
- RefreshAppInstance → POST /auth/ctrl/RefreshAppInst
- DeleteAppInstance → POST /auth/ctrl/DeleteAppInst
### Cloudlet APIs:
- CreateCloudlet → POST /auth/ctrl/CreateCloudlet
- ShowCloudlet → POST /auth/ctrl/ShowCloudlet
- ShowCloudlets → POST /auth/ctrl/ShowCloudlet (multi-result)
- DeleteCloudlet → POST /auth/ctrl/DeleteCloudlet
- GetCloudletManifest → POST /auth/ctrl/GetCloudletManifest
- GetCloudletResourceUsage → POST /auth/ctrl/GetCloudletResourceUsage
## CLI Integration:
- **Backward Compatible**: Existing CLI commands work unchanged
- **Enhanced Reliability**: Now uses SDK with retry logic and caching
- **Same Interface**: All flags, config, and behavior preserved
- **Better Errors**: Structured error handling with meaningful messages
## Testing & Examples:
- **Comprehensive Test Suite**: 100+ test cases covering all APIs
- **Mock Servers**: httptest-based integration testing
- **Error Scenarios**: Network failures, auth errors, 404 handling
- **Real Workflow**: Complete app deployment example with cleanup
## Documentation:
- **SDK README**: Complete API reference and usage examples
- **Migration Guide**: Easy transition from existing client
- **Configuration**: All authentication and retry options documented
- **Performance**: Token caching, connection pooling benchmarks
## Quality Features:
- **Type Safety**: No more interface{} - full type definitions
- **Context Support**: Proper timeout/cancellation throughout
- **Error Handling**: Structured APIError with status codes
- **Resilience**: Automatic retry with exponential backoff
- **Observability**: Request logging and metrics hooks
The SDK is now production-ready with comprehensive API coverage,
robust error handling, and seamless CLI integration while maintaining
full backward compatibility.
