- FCacheRecord must now be created by FCacheRecordBuilder.
- FCacheRecord values are always an opaque buffer now, and ECacheRecordType has been removed.
- FCachePayload has been added as a common type for the cache record value and attachments.
- FCachePayloadId has been added as a 12-byte identifier for cache payloads.
- ICache::GetAttachments is now GetPayloads and can fetch both values and attachments.
- ECachePriority::Blocking has been added for requests that the caller will block on.

Add queued work priority support to auto delete async tasks and schedule DDC Puts as Low priority
ThreadPool threads are now honoring the names they've been given on creation
Move the I/O only async DDC Get into the DDC ThreadPool with higher priority (Normal) than DCC Puts

Added stats for Cloud based DCC ( ie Jupiter ) to DDC.Summary
Added BackEnd name to DDC.Summary
Added HasLocalDDC, HasSharedDDC, HasCloudDDC to DDC.Summary

Also made Jupiter a slow backend, as this generally is closer to the typical speed people have to it. We should make this automatic based on the latency we find from the health check call.

ICache will eventually replace the existing cache access functions on FDerivedDataCacheInterface. The notable differences relative to the existing interface are:
- It is asynchronous with completion callbacks by default, and allows waiting when necessary.
- It allows batch requests containing multiple cache records by default.
- It uses a structured cache key made up of a bucket name and a hash.
- It supports prioritization and cancellation of requests.
- It supports structured cache records with metadata.
- It supports attachments to allow multi-part cache records.
- It uses a typed request object instead of an opaque integer handle.
- It provides cache policy flags to control how to query and store cache records, and which parts of a cache record to fetch.
This initial implementation of ICache is totally synchronous and uses the existing cache backends for storage.

The async put backend now uses this new status to avoid calling CachedDataProbablyExists after every put, which has a high cost for certain backends.
