Handle http error 429 too many requests

See original GitHub issue

Describe the bug We’re using coil version 2.0.0-rc02. We use coil to display thumbnails in an image gallery. When we use the fast scrollbar to browse images, we sometimes receive an http error 429 “too many requests” from our backend because we loaded too many thumbnails in a short amount of time.

To Reproduce

Create an image gallery with a lot of images
Add a scrollbar
Browse quickly enough using the scrollbar to trigger more requests than the backend can handle (e.g. go up and down quickly using the scrollbar)
Observe that some pictures thumbnails api call failed due to “too many requests” http error 429

Okay I understand @colinrtwhite but I think it’s a pity that coil doesn’t do it automatically, as I didn’t have this problem with glide. It would be interesting to have an extension for recyclerview that limits the loading from remote when scrolling.
