Extend library to new types of event

[kons-jaf]

Background

Defining an Avro schema for records to publish to Kafka is well suited for activity-events from ID-porten components or token-events from components authenticating with Maskinporten.

However we may want to facilitate publishing records

• without a pre-defined schema
• to their own topic
• with core attributes set

Specifications

Implementation should focus on simplicity of use:

• create a ProducerRecord based on a POJO not generated from an Avro schema
• enrich the record with static configuration data like application name and environment
• send the record to a configurable topic
