- [ ] CI/CD

## Description
<!-- Describe your changes in detail -->
Add `network_transaction_id` column in the `payment_methods` table as it is required to store the NRID against the respective payment_method_id. This NRID will later be used processor agnostic MITs. This pr also adds application level config (`network_transactoin_id_supported_connectors`) that contains the list of connectors that support the `network_transaction_id`.

### Additional Changes

- [ ] This PR modifies the API contract
- [ ] This PR modifies the database schema
- [ ] This PR modifies application configuration/environment variables
