[rajaneeshk90]

Description

Networks created using Beckn Onix use two layers of configurations for the request and response validation in a transaction.

As part of this PR, an example layer 2 configuration for the mobility on demand rides use case is created.

Changes

1. Added domain rules in the OpenAPI document "api/l2-config/mobility_ondemandride_1.1.0.yaml".
2. A postman collection, to be created to test the network rules added in the layer 2 config.

Tools needed to test this PR

Postman Desktop or Web Application.

How to test

1. Import the postman collection inside the "api/l2-config/postman-collection-test-cases/ folder into the postman application.
2. The postman collection contains requests, these requests are to be named in a way that clearly conveys their intended purpose.
3. Send the requests to verify that the added rule are working as expected.

Notes

This is an example configuration for a Layer 2 network. Network facilitators setting up a new network may use this as a reference. Adjustments may be necessary to suit specific network requirements and conditions.
