Tiles are cached by url template in the database

[wibge]

Tilesets are cached by url template, if the url to a tile source changes previously cached and downloaded maps are not seamlessly loaded.

We have tile sources that have frequently changing API keys as part of the URL.

Platform: ios
Mapbox SDK version: 3.4

Steps to trigger behavior

1. Create a tileset with a URL containing an API key
2. Cache tiles from the tileset
3. Change the API key in the URL

Expected behavior

Cached tiles are displayed when the tileset is on screen

Actual behavior

Cached tiles are not displayed

I'd propose adding an optional tilecachekey parameter to use to override caching by url template.

#8084 adds a feature that provides the ability to modify the URL independently of the value used for a cache key. Per #8041 (comment), I believe this addresses your use case.
