Add security package for authentication microservice and security configuration #1

Overview

Implement a security package that provides:

1. Authentication Microservice

   • Allow users to define their own token generation logic.
   • Generate and store JWTs against random tokens in Redis.
   • Internal GRPC communication for refreshing JWTs.

2. Security Configurator Package

   • Provide a security layer and a User Details Schema.
   • Allow microservices to retrieve user details from stored JWTs without exposing security logic.
   • Enable GRPC communication with the authentication service to refresh tokens.
   • Offer a wrapper around the httpx package to ensure secure inter-microservice communication.

Requirements

• Modular and extensible design for both authentication and security configuration.
• Simple integration guide for both use cases.
• Example implementations for both GRPC communication and httpx wrapper usage.

This feature will improve authentication and communication security across microservices by centralizing token management and providing a unified security layer.
