Additional Changes

• This PR modifies the database schema
• This PR modifies application configuration/environment variables

Motivation and Context

To support connector integration without auth details.
Closes #2895

How did you test it?

Postman.
Payment Connector - Create and Payment Connector - Update now supports a new auth type called TemporaryAuth and a new field status.

curl --location 'http://localhost:8080/account/merchant_1700133263/connectors' \
--header 'Content-Type: application/json' \
--header 'Accept: application/json' \
--header 'api-key: test_admin' \
--data '{
  "connector_type": "fiz_operations",
  "connector_name": "paypal",
  "connector_account_details": {
    "auth_type": "TemporaryAuth"
  },
  "status": "inactive",
  "disabled": true
}'

If TemporaryAuth is used in the request, the status field cannot be active and disabled cannot be false. This is applied for update mca as well. If a connector is inactive it cannot be enabled without changing the status to active.

There are the following error messages that will be thrown if incorrect request is used.

auth_type	status	disabled	error_message
TemoraryAuth	active	*	Connector status cannot be active when using TemporaryAuth
TemporaryAuth	inactive	false	Connector cannot be enabled when connector_status is inactive or when using TemporaryAuth
ValidAuth	inactive	false	Connector cannot be enabled when connector_status is inactive or when using TemporaryAuth

If all the fields are passed correctly you will a normal mca response.
