feat(core): warn about unused services in connections
Description
In XML configurations, we can declare connections on services that do not exist. Over time, when we remove services in a configuration, we may forget to remove its configurations, which pollutes the file.
Functional specifications
We should raise an error when an undeclared service is used in a connection.
Technical specifications
Do it when parsing connections in the app_config_manager
.
Test plan
As this is a simple SIGHT_ERROR, this can not be unit-tested. We will rely on manual test.
