New and Improved Entity and Participant Service

Here's a nice improvement for you!

With this release, we included the requestId, uniqueCode, and errorCode attributes to standardize the Entity and Participant Service Payload for callback and event notification. Previously, CoreOS maintained two schema structures. With this improvement, the payload schema becomes the same across notification topics and callbacks. This allows Kafka apps to switch over to the callbacks without modifying their handler parser logic. Learn more about Entity and Participant Services.
