Allow using service delegators only on console dependencies if you need

Is your feature request related to a problem? Please describe.
When you need to decorate a service with a delegator, you must add its config in the key "delegators" who is always loaded, for both the HTTP app and the CLI app. Sometimes, you may not want to decorate the service before reaching the CLI config. With this approach, you can't do it.

Describe the solution you'd like
Allow "delegators" key inside console config key "console".

Additional context
For example, this is a problem when you want to extend the behavior of the CLI from an external package.
