Part of an effort to make Kopf-based operators more stable and resilient.

Issue : #13 #142

Description

E2E tests are flaky and unstable. This PR makes them more stable by:

• Running in a standalone mode (on the same minikube as other, probably failed tests — to prevent freezing for minutes).
• Limiting a time of termination of a background operator to 60s (and adding this feature).
• Using a dynamic pod name in the pod-involving e2e tests (otherwise, it hits "409 Conflict" — when the pod already exists in the same cluster (actual for the local runs)).

Types of Changes

• Bug fix (non-breaking change which fixes an issue)
• Refactor/improvements
