✨ Is922/add autorecharge functionality

[matusdrobuliak66]

What do these changes do?

• ✨ Introduce auto recharge functionality to the Payments service

NOTE: Introduced variable PAYMENTS_AUTORECHARGE_ENABLED to the Payments service. Based on this variable we pay via the payment gateway (pay_with_payment_method). It is a temporary solution so we can turn on/off this functionality.

• Auto recharge concept: Payment service subscribes to RabbitMQ and listens on the wallet credits events. When the message comes, the Payment service starts to process the message, there are a series of steps to check whether the auto recharge should be done, if some of them are not met the auto recharge is not done.
  • Step 1: Check if wallet credits are below the threshold
  • Step 2: Check auto-recharge conditions (whether auto-recharge is enabled for the concrete wallet)
  • Step 3: Get Payment method
  • Step 4: Check spending limits (if the user set monthly limits)
  • Step 5: Check the last top-up time (Protective measure: As Payment service can in theory receive multiple messages, we need to make sure, that we do not initialize top-up multiple times. The current approach is that we allow just one top-up in 5 minutes, which should be reasonable for now)
  • Step 6: Perform auto-recharge
