Update nginx image for the nginx-https example

[dennisvang]

The nginx-https example (currently _archived) refers to two different nginxhttps images:

examples/_archived/https-nginx/nginx-app.yaml

Line 39 in 0598f07

image: ymqytw/nginxhttps:1.5

examples/_archived/https-nginx/Makefile

Line 18 in 0598f07

PREFIX = bprashanth/nginxhttps

Would it be possible to base this example on the official nginx image instead?

The additional bit of nginx configuration required for https would help to clarify what's going on.

Note, actually, the Dockerfile already is based on the official nginx image:

examples/_archived/https-nginx/Dockerfile

Line 15 in 0598f07

FROM nginx

and I assume this is supposed to be built using make container:

examples/_archived/https-nginx/Makefile

Lines 27 to 29 in 0598f07

	container:
	docker build --pull -t $(PREFIX):$(TAG) .

but none of this is clear from the readme.

This example is essential for people following the tutorial on https://kubernetes.io/docs/tutorials/services/connect-applications-service/#exposing-the-service
