Subject: [PATCH] tests/k8s: add new_pod_config() to lib.sh

Copied the new_pod_config() and pod-config.yaml.in from CCv0 branch
tests' integration/kubernetes/confidential/tests_common.sh and fixtures.
Unlike the original version, new_pod_config() now gets the runtimeclass
by parameter as the RUNTIMECLASS environment variable seems not broadly
used on main branch's CI.

The pod-config.yaml.in was changed as the diff shows below. In
particular the imagePullSecrets was removed to avoid it throwing a
warning on the pod's log.
