Wait for contour-operator deployment instead of pod (#41)
Wait for contour-operator deployment instead of pod (#41)

kind-e2e waits pods to be up by `kubectl wait pod
--for=condition=Ready -n "contour-operator"` but it gets error when
any pods are not created yet in the namespace.
The script is failing sometimes due to the issue:
e.g. https://github.com/knative-sandbox/net-ingressv2/runs/2418620924?check_suite_focus=true

Hence, This patch changes it to wait Deployment to be Available.
