Config changes messages logging

As the latest dev branch is 11.x. Changed to 11.x.

This component is called 'config' and 'config_sync' for logging currently on the dev branch. It's unclear which to pick here.

Is there a reason you did not inject the logger?

I think we just missed that it would be better to inject it.

Hm, this then needs also update on Drush side if we're going for injection.

We should follow the deprecation protocol we've had in multiple places, use DI, make it nullable and throw a deprecation (and instanciate the service) when the argument is null.

Are we sure we want to do this logging? It might be a lot of additional logs written during config imports?

Any link to some PR's or commits where that "deprecation protocol" was used?

It was the only way to log if and when block was deleted.
