PR: feat(test): Support result saving functionality for multiple storage backends

Description

This PR introduces a robust, multi-backend storage system for test results. It replaces the legacy database utility functions with a unified interface that supports Local File, MongoDB, and PostgreSQL backends. This enhancement allows users to configure and switch between different storage solutions seamlessly based on their infrastructure needs.

Key Changes

New Features

• Multi-Backend Support: Implemented concrete storage adapters for:
  • localFile: Saves results to the local filesystem (JSON/CSV).
  • mongodb: Stores results in MongoDB collections.
  • postgresql: Stores results in PostgreSQL tables.
• Automatic Type Inference: Added logic to automatically infer and convert data types during the saving process, ensuring schema consistency across different backends.
• Resilience Mechanisms: Implemented connection management pools and automatic retry mechanisms specifically for MongoDB and PostgreSQL to handle transient network issues.

Refactoring

• Unified Interface: Updated capture_utils to utilize the new generic storage backend interface, decoupling business logic from specific storage implementations.
• Legacy Cleanup: Removed obsolete database utility functions and consolidated them into the new general result-saving mechanism.
• Configuration Overhaul: Modified the configuration file structure to support dynamic multi-storage backend definitions (e.g., selecting the active backend and providing specific connection strings).

Configuration Example

The configuration file now supports a storage section:

results:
  - localFile: # Save the storage results to a local file. The default formats are jsonl and csv.
      path: "./results"
  - postgresql:
      host: "localhost"
      port: 5432
      dbname: "ucm_test"
      user: "postgres"
      password: "123456"
      retry: 3
  - mongodb:
      host: "127.0.0.1"
      port: 27017
      dbname: "myapp"
      user: "root"
      password: "123456"
      authSource: "admin"
      retry: 3
