Request : Add docker-entrypoint.sh provided in the nginx image, so that environment variables can be used in the configuration

It would be nice to add in the image the docker-entrypoint.sh file and the docker-entrypoint.d folder which are provided in the nginx official image and add it as an ENTRYPOINT of the openresty image:

ENTRYPOINT ["/docker-entrypoint.sh"]

(see : https://github.com/nginxinc/docker-nginx/blob/f958fbacada447737319e979db45a1da49123142/mainline/debian/Dockerfile)

This will allow to use environnement variables in the configuration as described here :
https://github.com/docker-library/docs/tree/master/nginx#using-environment-variables-in-nginx-configuration-new-in-119 :)

Note that docker-entrypoint.sh may have to be adapted to support the "/usr/bin/openresty" command:

if [ "$1" = "nginx" -o "$1" = "nginx-debug" ]; then

-->

if [ "$1" = "/usr/bin/openresty"]; then

Compare the image Dockerfile with the linked nginx Dockerfile, then inspect the provided docker-entrypoint.sh and docker-entrypoint.d components. Done means the openresty image includes them, uses /docker-entrypoint.sh as its entrypoint, and supports the /usr/bin/openresty command and documented environment-variable configuration behavior.
