Summary:
Add a new StoreResult which wraps the std::string returned by RocksDB.
This replaces the std::unique<string> that LocalStore::get() used to return.
This lets us avoid a memory allocation. StoreResult can also represent a "not
found" result, so that this case can be processed efficiently without having to
throw an exception.
Additionally, StoreResult is move-only so we can't ever unintentionally copy
the string data, which is potentially expensive. It also provides APIs for
creating IOBuf wrappers, or moving the string to the heap so we can create an
managed IOBuf around it.
