User story:

As a user, I can configure Find Bar search so that results are relevant for me. For example, my site deals heavily with image assets so I want to see more assets in my results.

As a user, I don't want to see results from apps that I don't even have in App Launcher.

Acceptance criteria:

• I can turn ResultSuppliers on and off. This allows me to define what apps should be searched.
• Limit top results to 3 items. The number of top results is not configurable (in the minimum viable product).
• Limit total # of results to 100. Apply the limit in the back-end query.
• Make the number of results returned configurable in the result supplier configuration YAML, per supplier.
• Read the existing app permission configuration and apply it to Periscope.
