Improve action execution to have data in the action invocation success response

[Thisara-Welmilla]

Issue:

• Improve action execution to have data in the action invocation success response product-is#22360

With the custom authentication extension, the JSON response body for a successful action invocation will include authenticated user information under data. The data field can represent a class defined by the downstream component. A generic solution is required to deserialize this data payload, with its structure being determined by the downstream component.
