[FEATURE] Make console functional when T3 is not installed yet
[FEATURE] First implementation of CLI install

This adds a basic procedure to make a default install possible.
Advanced things like DBAL are not supported and it might be the case

[TASK] Refactor installation process

Make it more robust by executing the install steps

Remove run level call from command controller and
use individual command run levels instead.

Minor cleanup of output
