Move the code from Command execute to separate services

[LOBsTerr]

Issue title

We should use commands just to get input from users and pass it to the services which will handle the rest of the job for us

Problem/Motivation

It is the first thing recommended by the community of Symfony console to keep the Commands classes thin. It is kind of Controller in MVC pattern. Logic should be written in the separate services.
It will

• reduce dependencies between the Command classes
• reduce a responsibility of Command class
• increase reusability of the common services and decrease code duplication as result

Love to see this happening.

We should take one and discuss what will be the best path to approach it.
