Add search to Admin area

Problem to solve

The richness of configurability in GitLab is a great strength. However, it's often difficult to find the right setting in the Admin Area. Being able to search the settings would greatly reduce the amount of time spend on configuration.

Intended users

All users with access to Admin

Further details

As a user, I want the ability to search the admin section to find the setting I am looking for rather than having to manually scroll through.

Proposal

Permissions and Security

Documentation

What does success look like, and how can we measure that?
