This PR targets having an example of continuous integration with Ecotone and Symfony (Still looking for a professional smooth workflow :) ). So it ships:

• One cli command per domain command
• Integration tests for each
• Github workflow to run it "as a developer would"

I post it here in a wip state because I'm stuck: When I run my tests, events are correctly triggered but not async projections. This is not due to Phpunit itself but only to the APP_ENV as this issue occurs when I run a command on an event sourced aggregate only: https://github.com/jclaveau/php-ddd-cqrs-event-sourcing-symfony-ecotone/blob/testing_commands/src/UI/Cli/Ticket/PrepareTicketCliCommand.php

APP_ENV=test console app:prepare-ticket lala lolo

Event sourced Ticket prepare command generates a stream but, contrary to dev env, no asynchronous projection is added to the projections table (It's created but remains empty):

ecotone=# SELECT * FROM projections;
 no |         name          |              position              | state | status | locked_until 
----+-----------------------+------------------------------------+-------+--------+--------------
  1 | last_prepared_tickets | {"App\\Domain\\Ticket\\Ticket": 1} | []    | idle   | 
  2 | unassigned_tickets    | {"App\\Domain\\Ticket\\Ticket": 1} | []    | idle   | 
(2 rows)

ecotone=# \c ecotone_test 
You are now connected to database "ecotone_test" as user "ecotone".
ecotone_test=# SELECT * FROM projections;
 no | name | position | state | status | locked_until 
----+------+----------+-------+--------+--------------
(0 rows)

I wondered if it was due to the fact there is no container running projections in test env but when I try

APP_ENV=test /data/app/bin/console ecotone:es:reset-projection last_prepared_tickets

I get

In ProjectionNotFound.php line 20:
                                                                      
  A projection with name "last_prepared_tickets" could not be found.

Digging in the docs I tried some options without success: https://github.com/jclaveau/php-ddd-cqrs-event-sourcing-symfony-ecotone/blob/testing_commands/src/Infrastructure/EcotoneConfiguration.php

I'm not enough aware of Ecotone to know if this is a usage issue or a bug so let me know if a should open a bug on Ecotone's repo.

Thanks in advance!

This PR provides

• A makefile following the example of https://github.com/jorge07/symfony-5-es-cqrs-boilerplate/blob/symfony-5/makefile to provide a smooth workflow while discovering Ecotone.
• Adds /data/app/bin to $PATH so console is instantly available
• Applies chown 1000:1000 to all the vendor directory to avoid blocking due to failing chown on unfound /vendor/composer
• It also adds bash-completion and autocomplete for Symfony's console and composer to discover Ecotone available commands fastly
• An updated README to get this workflow easily

My main concern here is about dev vs production docker images and behavior in a Kubernetes environment (which I personally never used).

Hoping you will find it interesting!

Anyway, thank you for your inspiring work and open-sourcing it
