## Description
Partially resolves: https://github.com/vulcanize/cosmos-sdk/issues/14
Implements a [RocksDB](https://github.com/facebook/rocksdb)-based backend for the DB interface introduced by https://github.com/cosmos/cosmos-sdk/pull/9573 and specified by [ADR-040](eb7d939f86/docs/architecture/adr-040-storage-and-smt-state-commitments.md).
* Historical versioning is implemented with [Checkpoints](https://github.com/facebook/rocksdb/wiki/Checkpoints).
* Uses `OptimisticTransactionDB` to allow concurrent transactions with write conflict detection. This depends on some additional CGo bindings - see https://github.com/tecbot/gorocksdb/pull/216, https://github.com/facebook/rocksdb/pull/8526. We'll need to replace the `gorocksdb` module until these are upstream.
