Summary

Initially, the nginx configuration for the Alkane webserver role
used hardcoded port information to pass a request to Docker PaaS.

This change introduces a method to prepare a dictionary of proxy_pass URLs
per server and application, and applies it for API and infra.

Meanwhile, another change introduced a services table, but this change
allows to automatically handle host and port changes.

Test Plan

Deploy on Ysul

Rebased. Fixed pillar handling.

The output is really useful to avoid to manually repeat the ports.

But since salt-tower, we can't have a view from web-001 on the docker-002 pillar.

For example, if we run paas_docker.get_upstreams against docker-002, we've this dictionary:

{P396}

So, if we want to adopt this system, there is a need to consolidate the salt-tower files, by recreating the former unified pillar.

I've asked upstream for advice how to resolve pillar for another server than the current node @ https://groups.google.com/g/salt-tower/c/XEKg2CEiZrU
