Add admin settings to usage ping
Overview
GitLab's administration area is complex, with many settings. We need to go back to convention over configuration and see how we can simplify our settings by removing configuration wherever we can AND refactoring our current settings pages for usability.
To do this effectively, we need data on which settings instances are using. Which were set by default and never changed and which settings were changed and when?
Proposal
- Send an instance's admin settings over in the reported usage ping.
- If it's too much to send over all settings, we can consider just sending over settings that were changed from their default setting.
