Switch Zen cache store to use the HTTP request codepath in the Jupiter cache store while taking some of the improvements that had been made when that code was branched off to make the Zen HTTP codepath. This is a precursor for getting Zen cache store using non-blocking operations like Jupiter cache store - this has started to be stubbed in with the EnqueueAsyncRpc methods that are stubbed in but not used from the Zen cache store. Eventually I'd like this HTTP code to move out of the DerivedDataCache module and be usable elsewhere and supplant the HTTP code currently in the Zen module, but this will require some decisions about whether IRequestOwner should move out of the DerivedDataCache module or not.
Tested Zen operation using ShooterGame editor.
Tested Jupiter operation using CitySample editor (empty local cache).

This is being resolved by cherrypicking 19196840 by mark.lintott from UE5/Main (see original changelist details at the end of this cl description). On top of the cherrypick, there was a change made to re-use a single Http request when fetching stats. This avoids the overhead of doing name resolution repeatedly if the zen instance has a name instead of IP address.
Tested by:
- Running ShooterGame editor & observing UnrealInsights for ZenHttp_CurlPerform timers and ensuring they are not happening on the game thread when the editor is sitting idle (they are on background threads instead)
-Terminating ZenServer.exe while the editor is running and observing whether the framerate of the editor is negatively affected

Re-use Curl request when gathering stats. Rate limit it to no more than 2/second. Still keeping it synchronous and blocking for now.
Avoid using "localhost" and prefer the IPV6 loopback address of [::1] to avoid name resolution penalty for localhost.
Keep DNS cache in Curl permanently for a given request.
