ConfigurationServiceProvider migration

Bug Report

Seems like ConfigurationServiceProvider have been removed as part of this PR, but there are a few left-overs:

• there are still references to the class in the docs: https://github.com/search?q=repo%3Aoperator-framework%2Fjava-operator-sdk%20ConfigurationServiceProvider&type=code
• I'm unable to find a "migration guide"

Good catch, it was mostly an internal component, will fix the docs.

I'm looking for a way to replace those lines:
https://github.com/Apicurio/apicurio-registry/blob/e4f48bae6ab0e434e8e4b59525632b0afd888e4a/operator/controller/src/test/java/io/apicurio/registry/operator/it/ITBase.java#L170-L172

which are similar to the test infrastructure of Keycloak, cc. @shawkins

you can just simply use the override param when creating the operator. See changes in docs :)
