Default to miq_messaging for event_handler

[nasark]

• picking up and continuing from https://github.com/ManageIQ/manageiq/pull/21361
• set Kafka as the default messaging_type for events

i.e.

nasarkhan@Nasars-MacBook-Pro manageiq % kafka-console-consumer --bootstrap-server localhost:9092 --topic manageiq.ems --from-beginning
{"event_type":"test_action","source":"IBMCloud-VPC","username":"nasar123","ems_id":1,"ems_ref":"abc","timestamp":"1234","vm_uid_ems":"vm","vm_ems_ref":"vm_ref"}
{"ems_ref":"event-ref","ems_id":34000000000941,"event_type":"STUFF_HAPPENED"}

Depends on:

• [ ] https://github.com/ManageIQ/manageiq-schema/pull/655

I'm wondering if we need the schema changes at all. I don't think there's an expectation of upgrading prototypes as being supported.
