Backend to return plugin sections data for home page

[codemonkey800]

Create a backend endpoint to return various sections of the homepage consistently.

How often do we refresh the sections?

We would utilize the 5-minute cache of API response to handle the data refresh

How do we handle duplicates across the sections? What is the priority for sections?

We build out sections that don't require random sampling first and use that to remove duplicates in the randomly sampled section.

reminder: we're not including theme as part one of the random plugin data types

API Contract for endpoint: https://docs.google.com/document/d/1Md39pS3v7yP8a7fNb6qfAmFY4arVUjIuJZTi3JVz9hw/edit#

The endpoint should be API key protected.

curl -X GET --header "X-API-Key: secret-api-key" https://api.napari-hub.org/plugin/home/sections/foo,bar,baz

The API key will be made accessible to the frontend at runtime.
