Kafkasql storage does not properly handle the owner field.

[carlesarnal]

The KafkaSQL storage is fetching the owner in the sink thread, which causes it to be empty since this value is only available in the HTTP request thread.

[pwright]

@carlesarnal what's the workaround? eg Do not set owner-only-authorization ?

Note: https://www.apicur.io/registry/docs/apicurio-registry/2.3.x/getting-started/assembly-configuring-the-registry.html has mention of this property, but seems to have been removed some time later.

apologies, it's in v3 doc at https://www.apicur.io/registry/docs/apicurio-registry/3.0.x/getting-started/assembly-configuring-registry-security.html#registry-security-obac-enabled
