> The {{/recommendations}} and {{/validations}} endpoints should support actions "configurations",
"configuration-dependencies" and "component-layout" for config-groups. This involves making
the calculations for defaults and validations, using only the hosts for that config-group.

> API has to check the presence of {{config_groups}} in the "recommendations" bag, and
use only those hosts for calculations. The response would return the changes inside the same
{{config_groups}} object as written in document. The inner property {{configurations}} contains
changes local to the config-group. The inner property {{dependent_configurations}} contains
changes outside of the config-group.
