MQ message structure

✏️ WIP

(어느 정도 안정되기 전까지 자주 변경될 수 있음)

{
  entityName: <string>
  entityId: <string>
  publishSource: <string> // typically application identifier
  actorType: <string>
  actorId: string
}

// Example - (topic = "cafe", name = "create")
{
  entityName: 'cafe',
  entityId: '<cafe-id>'
  publishSource: 'coffee-hmm-http-api@0.1.7-beta',
  actorType: 'user',
  actorId: '<user-id>'
}
