Prefix all cache keys via SWRConfig

[SokratisVidros]

In a multi-session application that works similarly to Gmail the data of a /v1/emails endpoint should be cached per session (or user). In Clerk, we have a similar scenario, and we append the session_id as a query parameter to the cache key /v1/emails?session_id=42 to prevent the stale data from one session from flicking into another.

It would be great to prefix all cache keys globally with the session_id and make useSWR invocations more straightforward.

Is there maybe a better way to address this without having to provide a custom cache implementation?
