Description

Added an event each time a payment capture happens with the relevant contextual info

• Pass along request_state to payment_core
• Modify the UpdateTracker trait to accept request state
• Modify the PaymentCapture implementation of UpdateTracker to generate an event
• Showing the capture_amount and multiple_capture_count fields in the event
• Added tenant_id field for the event

Additional Changes

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

Motivation and Context

To generate audit events whenever the payment state changes so we can get a brief overview without needing to comb through the logs.

How did you test it?

• Implemented an event trigger that activates whenever the payment capture API is utilized. This event triggers an audit event, the details of which are subsequently reflected in the Kafka UI.
• Create a payment & then capture it.
• Fields that need to be tested are: capture_amount, multiple_capture_count and tenant_id.
