metrics: stops kata components and k8s deployment when test finishes

Browse Source 
This PR adds a trap whenever the scrip exits, it deletes the iperf
k8s deployment and k8s services, and deletes the kata components.

This way, when the script finishes, it verifies that there are
indeed no kata components still running.

Fixes: #8126
