User Popover

The frontend case for removing job_title and organization from the /api/:version/users/:id endpoint

This is where the frontend API call is made from: app/assets/javascripts/api.js

The only place this call is being made is in app/assets/javascripts/lib/utils/users_cache.js

The only three components that use app/assets/javascripts/lib/utils/users_cache.js are:

• app/assets/javascripts/user_popovers.js
• app/assets/javascripts/filtered_search/visual_token_value.js
• ee/app/assets/javascripts/vulnerabilities/components/app.vue

Of those the only file that references organization or job_title is app/assets/javascripts/user_popovers.js

Update: job_title and organization can't be removed because this a public facing API
