Entity model for streaming applications or microservices

Is your feature request related to a problem? Please describe.

We are currently abusing DataFlow and DataJob entities for modelling streaming applications, however we found the paired entity model forces unnecessary complexity.

Describe the solution you'd like

I would like an entity model for continuously running applications such as kafka streams applications or microservice applications in event-driven architectures.

Describe alternatives you've considered

As said before, we are currently abusing DataFlow and DataJob entities. DataProcess existed in the past and was quite nice, however it was deprecated.

Recent features in Datahub make easier to define custom entities, however we found that this use case is general enough and so it could be included in the default model.
