- Implemented only for the structured cache initially.
- Records are stored as compact binary packages with payloads stored within the record if small enough.
- Records are stored in Records/{Bucket}/{01}/{23}/{456789abcdef0123456789abcdef01234567} based on the hash in the cache key.
- Content that exceeds the size allowed for storage within the record is stored in Content/{01}/{23}/{456789abcdef0123456789abcdef01234567} based on the hash of the content.
- Both records and content are written to disk with their hash as a suffix, and are always checked on load.
- Maximum size of compressed data stored in the package can be configured by MaxRecordSizeKB and MaxValueSizeKB.
- Maintenance of the cache, to delete unused files, has been rewritten and can now scan ~175k files/second on modern hardware, though is limited to 10k files/second in the config to avoid adding too much overhead.

When ServerID is used, configuration is first loaded from a key matching the ServerID field, in the HordeStorageServers section of the same INI. This makes it easier to put Jupiter configuration in a consistent place and have it stripped by the cooker to avoid leaking any of the configuration.

Any function that may create a request now has a IRequestOwner& parameter, and uses the Begin and End functions on the owner to manage the lifetime of any requests that it creates, as well as using End to invoke the completion callback for any request which has one.
The new FRequestBarrier may be used to block a group from being considered complete in a scope where more requests may be added to it.

This allows the new cache to be implemented more efficiently using the old cache backends because functionality like the corruption wrapper and key length limiter can be bypassed and the individual backends can store cache records in whatever way is most efficient for them.
The hierarchical backend may request payloads when they are not required due to incomplete tracking of backend state, and GetPayload will never fill other backends due to the inefficiency of the existing backend framework.
The filesystem backend does not cache any state in memory, which makes requests for individual payloads less efficient than if it cached a mapping of cache payload key to raw hash after the first request for a cache key.
The HTTP, S3, and pak file backends are not implemented for the new interface.
The backends do not implement ICacheStore::CancelAll() because the existing backend framework provides WaitForQuiescence to wait for completion of async requests, and the implementation of ICacheStore by those backends works with that mechanism.
The non-leaf backends (hierarchical, async put, etc.) do not update stats from the ICacheStore functions.

Still allows build machine runs to be thorough about completing PUTs.
Doesn't interrupt any in-flight PUTs, just prevents processing of any remaining queued PUTs.

Changed the Dev toggle for CookCompare to use this.
This can also be used to locally toggle Jupiter to run against a local deployment.
