{Core} Expose public interface for SecretStore

[jiasli]

Description

Expose public interface for using encrypted SecretStore so that command modules or extensions (such as calvinsID/azure-cli-extensions#97) can leverage msal-extensions to save custom data such as tokens.

Testing Guide

On Windows:

> az demo secret-store save "name=Johann Sebastian Bach" job=musician
Data written to C:\Users\username\.azure\secret_store_demo.bin: {'name': 'Johann Sebastian Bach', 'job': 'musician'}

> az demo secret-store load
{
  "job": "musician",
  "name": "Johann Sebastian Bach"
}

Turn off token encryption:

> az config set core.encrypt_token_cache=False

> az demo secret-store save "name=Johann Sebastian Bach" job=musician
Data written to C:\Users\username\.azure\secret_store_demo.json: {'name': 'Johann Sebastian Bach', 'job': 'musician'}

> az demo secret-store load
{
  "job": "musician",
  "name": "Johann Sebastian Bach"
}

A good solution for SecretStore

This works as expected when I try with our setup here (caching GitHub credentials for the containerapp extension). Thanks!

@rayluo, CLI is helping msal-extensions have more users! 🤣
