Ingress operator canary health checks failure

[returntrip]

I am having an issue where the ingress-operator for the hosted cluster is unable to perform canary health checks. If I unset the HTTPS_PROXY within the ingress-operator pod then I can curl into the canary healthcheck endpoint.

I believe this PR should take care of this issue, but in my case it does not seem to work: #1131
