deploy: Remove no longer existing orchestrator
This removes the orchestrator definition from our manifests.
That does not deploy yet those changes, nor clean up the dangling files on machines. That'd need to be done at that time (manually).

Test Plan
- deploy on puppet master (pergamon)
- sudo puppet agent --test
- deploy, clean up dangling files
- sudo puppet agent --test --noop ~> no new diff should show up
