- In this PR I extract from the crate `db` to the new `storage` crate all traits that is not specifically related to the concrete implementation of database. So I now can use `verification` crate without `rocksdb` dependency.
- Also I modify the `HeaderAcceptor` so that can be constructed without the private `BlockDeployments`.
