serve provenance with "alien" issue

[DanielMorales9]

What is the desired change?

kaos serve provenance on a running endpoint with an “alien” model will give an Exception. This should be improved in order to make kaos more flexible - the “alien” model should behave like a “kaos model”.

How will this change improve kaos?

Provenance will not "break" when using an external/alien model.

Any thoughts on the implementation approach?

• separate template DAG for serve
• expand integration test for an “alien” model
