Be able to map kafka topics to event handler functions, and also to importer modules that handle those events.
Examples:
- ciindexeradmin -> ES (workspace indexer)
- workspaceevents -> RE (workspace importer)
- sampleservice -> ES (sampler indexer)
In this case, there is a separate event handler function and importer module for ES/workspace, ES/samples, and RE/workspace.
Right now, the events for workspace-to-RE and workspace-to-ES are handled by the same function. It may make sense to separate them out.
