What this PR does / why we need it:
The testmachinery controller implements some basic garbage collection to clean-up pods related to completed workflows. Even though the controller deploys workflows into different namespaces, it tries to find any pod in its own namespace.
This PR changes the behavior to look into the namespace of the actual workflow for garbage collectoin.
