Https

[jonathanjfshaw]

In #55 you added a readiness check to nginx.

It uses httpGet on port 80; it needs to be configurable to use port 443 and specify https as the 'scheme' or it fails nastily with intermittent 503 errors if an ingress is used that forces https.

See https://kubernetes.io/docs/tasks/configure-pod-container/configure-liveness-readiness-probes/#configure-probes for docs

I would make a PR but I'm not sure how you're planning to setup https, how you want to arrange the values.yaml for that.

TLS is going to be terminated in ambassador, internal comm will be 80 (at least for now). I believe we can add expose probe scheme and port as variables.

The TLS is one of the next tasks in queue now.
