Allow configure `default_config` from UI

I was thinking that it would be great to have a checkbox (maybe in config/core) that allows users to choose whether or not they want to use the default_config

It would also be nice if the integrations activated by the default_config are shown. It could be displayed as a nested list of checkboxes so this way users could disable the default_config and select which integrations to activate. It would also serve to know which integrations are included with the default_config

This check (active by default) could be offered to user during onboarding proccess.
