Enable additionalProperties for kafka topicConfigurationObject

[gokerakc]

Reason/Context

Currently, only 5 topic configuration properties are supported by the asyncapi kafka binding (json schema here).

These properties are;

• cleanup.policy
• retention.ms
• retention.bytes
• delete.retention.ms
• max.message.bytes

But in some cases, there is a need to specify vendor-specific topic configurations (e.g. confluent-topic-configs). For that reason I think it makes sense to increase the version of that binding and enable additionalProperties for the topicConfigurationObject.

In my use case, I need to use the following additional properties and they can also be added to the topicConfigurationObject if you see a good fit. Please see the properties from the vendor and proposed property names for the topicConfigurationObject:

• confluent.key.schema.validation (schema.key.validation.enabled)
• confluent.key.subject.name.strategy (schema.key.lookup.strategy)
• confluent.value.schema.validation (schema.value.validation.enabled)
• confluent.value.subject.name.strategy (schema.value.lookup.strategy)

Please share your thoughts about enabling additional properties and adding these optional properties to the object.

@lbroudoux I would like to get your thoughts on this because you commented about adding new properties before.
