Add Asgardeo password migration sample

[ThaminduDilshan]

Purpose

When a customer is onboarding in cases where they are migrating from an existing IAM solution, it is required to move their user base to WSO2 Identity Server/ Asgardeo. In most of these systems, users have credentials (passwords) in a system preferable manner and are unable to export them to a different system. One major challenge is there’s no standardized way to communicate with external systems in these sorts of requirements. Therefore when dealing with external systems, we need to handle different types of request and response formats. The proposed solution utilizes a conditional authentication script and an external REST service which exposes a few API endpoints (ex: Choreo) to perform the user authentication with the existing system.

This PR adds the Ballerina sample project for the external authentication service which can be deployed in Choreo.
