refactor docker-compose to make it easier

[dovholuknf]

the docker-compose example is a learning tool, but people seem to be more interested in simply deploying an overlay quickly and easily and not so much for complex learning. relegate the current docker-compose to a learning tool by flipping the simplified-docker-compose.yml with the existing docker-compose.yml. Then, refactor the doc to focus on the new, easier, experience.

Also, refacotor the compose file to incorporate ALPN and radically simplify the .env file down to the most basic pieces. Example .env and compose files are located at https://github.com/dovholuknf/ozconfigs/tree/main/extrasimple for inspriation. .env file is much simpler and basically requires changing adding/changing/providing these values:

ZITI_FULLY_QUALIFIED_DOMAIN_NAME=cdaws.clint.demo.openziti.org
ZITI_CTRL_PORT=8441
ZITI_ROUTER_PORT=8440
ZITI_USER=admin
