BackupCacheStore class

A store that reads from a primaryStore first, and then from a backupStore.

The resulting futures form all operations are the ones from the primaryStore. The backupStore operation are launched but not awaited (except for get).

When getting a value with get, if a cache value exists in backupStore, but not in primaryStore, it is saved to the primaryStore before returning the loaded value.
