Add test-identifying annotations to e2e resources (#2701)

Inject e2e.olm.operatorframework.io/feature and
e2e.olm.operatorframework.io/scenario annotations into every resource
applied during an e2e scenario. This makes it possible to identify which
feature file and scenario produced a given resource when debugging test
failures on a cluster.
