Update Xdebug enabled PHP container to match the production one

[DiegoPino]

What?

Our xdebug specific container is outdated and does not match in PHP version nor client utilities the one in production.

Also, we may want to adapt/change the way the IP address is exposed (host.docker.internal does not exist in Linux) by using something like:

@pcambra thanks!

Solution:

• match them. Edit/adapt/add a new entry point script, build it and push it to docker hub
• Update docs in https://github.com/esmero/archipelago-documentation/blob/1.0.0-RC1/docs/xdebug.md to cover (and test) debug in Linux

Just to leave here the setup I've used to make it work:

    environment:
      - XDEBUG_CONFIG="remote_enable=1 remote_host=172.18.0.1 remote_autostart=1 discover_client_host=1"
      - PHP_IDE_CONFIG="serverName=docker-debug-server"

It is possible that the remote_autostart key would be enough, according to https://stackoverflow.com/questions/46263043/how-to-setup-docker-phpstorm-xdebug-on-ubuntu-16-04

But from the article above, the entrypoint could have something like:

#! / usr / bin / env bash
# entrypoint.sh
set -euo pipefail # quit on errors
export XDEBUG_CONFIG = "remote_host=$(ip route show | awk '/default/ {print $ 3}')"
exec "$ @" # execute the rest of the command line

It is also possible that the DBGp settings are required for PHPSTORM:
