Adds cluster setting to allow caching requests with size>0 in request cache #16484

Description

Adds a cluster setting, indices.requests.cache.enable_for_all_requests, which controls whether to allow caching requests with size > 0 in the request cache. Defaults to false, matching previous behavior.

Since tiered caching can make the request cache significantly larger, it can make sense to cache these requests. This setting probably shouldn't be turned on if tiered caching isn't in use.

Tested in UT, IT, and manually tested turning the cluster setting on and off while checking whether requests were cached.

Why is adding a new setting not something that should be documented or added in the change log?

My mistake, I thought this was only for larger changes. I'll add it to the changelog.

It may also need to be updated in the documentation.
